question: Good afternoon, Monday, I engaged in sexual practices with a lady which included her rubbing and masturbating my erect penis, me sucking on her breasts---which I tugged with my teeth, since she wanted me to bite them---and her grinding against my body while being on top of me while my erect penis was exposed. She was wearing jeans while this was happening, but after about 20-30 seconds I had her get off of me since my penis was exposed and her crotch area seemed moist. Also, she licked and kind of bit on my nipples off and on for about 1-2 minutes. Furthermore, she fingered herself while laying on her back a few minutes later as I pulled, kissed, and tugged at her nipples with my mouth until she climaxed. But I refused to finger her, although she did lick both of her wet fingers after fingering herself a few times. I just don't remember if she played with her nipples with her fingers during the encounter, which makes me nervous because I am afraid I might've opened a channel for possible transmission by licking and sucking on her nipples. Also, when I pinched her nipples, I may have had cracked skin on my fingers, given how cold it has been in the Upper Midwest this week. I should also note that I have a broken tooth that has been filled until I get a root canal, and that I am going to the dentist next week to finish a root canal that they began last month on another tooth. Needless to say, I am scared of exposure through those channels as well. I also started thinking to myself that she might have fingered herself prior to my arrival at her home, and, perhaps she stroked my erect penis with the same hand unwashed. Obviously, the penis does have a hole. When she stroked me, I don't remember any pre-cum/cum, but it may have been there in microscopic amounts. She also told me last night that she last tested for HIV in March 2014, was negative, and that she only engaged in sexual activities with one other person since then, but I'm not certain what they did. Am I at risk of contracting HIV from the above practices, and when is the earliest that I can be tested? I am pretty nervous at the moment, and kind of scared.
