I did a stupid thing and visited one of those asian massage parlor. The lady gave me a regular massage and after started to lick the back and the buttocks area. and than she proceeded to give me a handjob while massaging my anus with the other hand. She washed her hands after the regular massage but she may had some saliva on her hand while massaging my anus. Is it possible to catch any of the STD including HIV this way. No other sexual contact besides what I have mentioned. Thank you in advancee
