We had unprotected anal sex with a man I met online. first he was rubbing my anus, then suddenly he tried to insert his penis into my anus with all his strength, it took 10 seconds at most. I pulled back my anus when I forced it, then he tried to insert his penis into my anus with all his strength, he forced it twice and both of them were in five seconds. 10 seconds total. It was as if he wanted to do it especially, but I was very hurt, it did not penetrate fully, he did not enter all the way, he could not enter anyway because he tried to enter by force. Maybe 5-10mm in. Do I need Pep?
