I am a married man, in Australia. I visited massage parlours/escorts for 12-13 times in last 6 months for body to body massages/hand jobs. Girls and I were naked and rubbed our bodies with each other. They used to touch my anus, penis, and scrotum, licked my nipples also it’s possible that during these encounters, my bare penis would have touched their vagina, anus, buttocks and breasts from outside, but I always masturbated myself in end. However I came by boob jobs couple of times and came on the massage girl’s body. Also I kissed some of them on lips, though these were not very long or deep kisses, but saliva exchange was there. I licked their boobs and kissed on body and buttocks. In all cases, either oil/cream was used. In last encounter, I felt that the lady appeared to be a transgender. I never fingered any girl, but would have touched the vagina and anus from outside. And there were never oral or any kind of penetrative sex.
What if they were infected with STDs or HIV, and had their saliva, vaginal secretions or some blood and then we did above activities, or I had some cut. Also I am not sure if they cleaned themselves after meeting other customers and also not very sure about the cleanliness levels of their sheets or towels.
My questions are below: 
1. Am I at risk of any STDs including HPV or HSV, Hepatitis B or C?
2. Am I at any risk of HIV? 
3. Am I at any risk for any other dangerous diseases?

Should I get myself tested? Can I have sex wd my wife without worry
