Someone recently used a fleshlight on me(I was the receiver). As I believed that you couldn't contract STD's from inanimate object, I wasn't too concerned but I now heard new information that it can spread STDs. They also put their own lube in this fleshlight. I have no idea whether or not this person used this fleshlight on themself right before this encounter. My questions are,
1. Worst case scenario, let's say this person did have an STD and used this fleshlight on themself 10 minutes before my encounter so it may still have been wet when they used it on me, am I at a high risk of getting an STD, provided this person did have one.
2. If their body fluids were in the lube they used for me, is this a risk or no risk? I heard all STDS can't live outside the human body for long but I was unsure how long. 

I was previously scrolling through other people's answers and they asked about the risk of contracting an STD from a purchased fleshlight. I too have purchased a fleshlight and lube online(this is different to the fleshlight and lube mentioned above) and it did also say it was able to be returned, so I was concerned that the returners might've sealed the product so it looked unopened and then sent it back and then the sellers gave me this used product.(I know this is a very extreme case) 
Q3. Let's say in an extreme case there was body fluids from an infected person in the purchased fleshlights+ lube, is there any risk of me acquiring an STD(HIV, HSV,HPV, syphillis, chlamydia, gonorrhea) from this. It took around 1 day for the products to ship to me( so it said it shipped on the 17th and arrived on the 18th) and I used the product immediately after it came. 

Thank you Doctors
I know this seems extreme but I do have severe health anxiety which makes it so random what if scenarios always pop up in my head. Should I get any STD test or no need? 

Welcome to the forum. I'm happy to address these issues.---

To answer your questions. I am a male and I meant a fleshlight which is a male sex toy, not a flashlight. 
To answer your questions. 
1. It was penile insertion. The fleshlight is like a toy vagina. I don't know whether it was washed after use, but I assume it would be with water but not sure about soap. Both males (me and partner). No penetration was involved, the only thing that happened was the fleshlight was used on me. I'm not 100% sure if this partner even used it prior to using it on me but let's say he used it like ~10-15 minutes before me and it was still wet, is this a high risk for transmission for any STD. How long do STD's(HIV, chlamydia, gonorrhea, syphillis, HSV, HPV) survive for outside the body? Also not sure if this person had an STD because I am no longer in contact with this person. 
2. The ingredients for the lube are propylene glycol, glycerin, purified waterm methylparaben, polyquaternium 15. Are any of these enough to kill the STD's. If so how long would it take for the STD's to die.
3. I think you mistook fleshlight as flashlight. Fleshlight's don't dry as quickly as a few minutes. Since this fleshlight took one day to ship, can STD's even survive this long outside the human body. 

Thanks and apologies for missing out on information.

Thanks for the follow-up comments and for clarifying the device. I didn't confuse fleshlight with flashlight, but I do have a clearer picture of the situation.---

Thank you Dr Handsfield!
The reason I was mainly concerned about the purchased sex toy(fleshlight) being used was because in the return policy, it said it could be returned within 30 days, had it not been opened. I know this is super super extreme but I imagined a scenario where the buyer resealed all the packaging carefully and made it as if it was brand new even when he used it once and returned it and then after this, the seller sold it to me. Q1. So would you say 24 hours is definitely long enough for the viruses & bacteria to have died in a closed, wet environment? 

2. Also is there any chance that transmission can happen if I used a tissue or wet cloth to wipe myself after this encounter. Once again, assuming that there was an infected person's secretions on this tissue/wet cloth. (let's say these tissues came from a box so a closed environment)

3. One more question is, I once went to a massage place and it was a happy ending place so I was fully nude lying down on the bed. If the bed wasn't cleaned after the previous customer came, is there any risk for my contracting any STD from just lying on the same bed assuming there was an infected person's secretions there.

I know all these scenarios seem very extreme but I just want to make sure. 
Thank you  

Just to add, I am mainly concerned about HIV, HSV, HPV (as from what I know these are the incurable ones) but I would still like to know the risk for all other STD's as well. I got the gardasil vaccine 6-7 years ago. I think it was the 4 as it was a triple dose one. 

Q4. One more quick question is how long should I wait before I test for each STD. (HSV,HIV, Syphillis, chlamydia, gonorrhea)

5. Also when you say "instantly inactivate all STD viruses and bacteria," that means the virus is killed and can no longer be transmitted/ no longer contagious right.

You're worrying needlessly about outlandishly unlikely scenarios. You are never at risk for STDs (including HIV) from any of the kinds of exposure you mention. Without direct vaginal, anal or oral sex with a live partner, you can safely assume you are at zero risk and do not need testing.---

So just to see if I am understanding what you are saying, the bought sex toy which even if in the very extreme situation was used and still had fluids when it was delivered to me and I immediately used it situation, the infected wet cloth situation and also sitting on the same infected massage table situation poses 0 risk at all. I am quite curious though, will all those viruses/bacteria have died within 24 hours while it was being shipping. Sorry if it seems repetitive but my anxiety will not ease until I know for sure I'm okay.
And, the only potential risk is from the sharing of fleshlight, only if my partner had ejaculated in the fleshlight and then I immediately used it? 

Thank you Dr Handsfield

I can't say how quickly any STD bacteria and viruses would die or become non transmissible. But I do know that no STDs or HIV have ever been reported to have been transmitted in this fashion. So I don't see that the biological reasons matter. You aren't at risk -- no point in wondering about it further, in my opinion. The last question is asking me to repeat what I have already said.
