I am 21 years old homosexual male and met a 50 year old man online and hooked up. Online, I asked him what his HIV and STD status was and he said negative and no STDs, respectively. To prepare, I shaved my pubic region around my testicles and penile shaft and around my anus. I cut myself slightly in 3 location on the front area just at my shaft's base and on my anus. I met with this unknown individual 4 hours later. Neither one of us kissed or had oral. The only tongue contact I gave was kissing his chest and neck. He then rimmed my anus for about 1 minute. Afterwards he fingered me with lube (he did so for about 25 minutes) and had anal sex with a condom. Because he was older he got soft periodically, about 8 times to be precise. So every time he pulled out, he took off the condom and stroked and then put it back on and continued (happened 8 times or so). He also spit in his hands and jacked me off with the lube. Afterwards, he was jacking off and ejaculated on my chest and then immediately after rubbed his penis on my anus for about 1 minute. Then he rubbed my penis with his cum in his hand. About 5 minutes later I jumped in the shower and rinsed with water and washed my anus with shampoo, slightly using my finger about 2 inches deep to clean it out. Considering that about 4 hours prior to having sex I had cut myself on the lower shaft and anus, that he rimmed me, rubbed his ejaculated penis on my anus, and then stroked me with cum on his hands after, I need to know the risks to this incident (it just happened 4 hours ago). Please guide me, I am scared. Should I go to the doctor and take the PEP immunization? As far as STDs, what should I be concerned with and what should I do? Thank you for everyone's time and consideration. It means a lot.
