So the other night I had an encounter with a sex worker and I am really worried about having an STD now. I received oral sex (with condom) and there was some vaginal sex too (again with a condom). There was no kissing involved and the only thing I am worried about is that I touched her private parts a little bit (I am worried about this because I read that some STDs like herpes can be contracted just by touch). It's been two days since this encounter and I think I don't have any symptoms (which doesn't really say something at this point though). As for the age of the sex worker, I would say she must have been around mid to early twenties (which is the same as me).
