Hi docs, I have an unusual situation, but it's literally killing me. Yesterday I was masturbating my self alone in a hotel room. It happens that I decided to use a plastic object as a a sex toy, putting it inside my anus. It is a like a plastic bottle, used to armazenate foot powder. I had bought it at a drugstore at the mall two hours before, and cleaned it with water and soap before inserting it into my anus. My biggest concern is that I may not have cleaned it the proper way (maybe the water didn't reach all the surface of it), neither used a condom. I am afraid that somebody at the store, or some other costumer, may have used it before me as an anal estimulator, or some evil mind had decided to put contaminate sperm or vaginal secretion on it, or some costumer touched it with bloods on hand. It took about two hours, between the time that I bought it and the time that I used it as an anal estimulator. It was pretty dry before I washed it. Is there any risk for HIV or other STI. Should I resume sex life with my wife, or should I get examinated before it? Thank you so much in advance. 

Welcome back to the forum.---

Thank you so much, Doctor!! One more redundant question, when you mean 'STD', HIV is included, alright? I mean, there's no way to get HIV as well from the situation above? 

Yes. In fact, HIV is one of the least easily transmitted STDs. Absolutely no risk for the events described above.---

THank you so much, Doctor ! I got no more questions !

Thanks for the thanks. I'm glad to have helped.---
