Anal experience

I hooked up with a guy about a month ago. It was the second time I hooked up with him and he had been wanting to try anal with me. I was kinda hesitant because I wasn't super comfortable with the idea of anything being shoved up that hole. When he started roughly pulling my hair and asking me if I wanted to be fucked in the ass, I told him that I was willing to try it. It took him a while to actually get it in because he wasn't super hard, but when he finally did get it in (without lube btw-- biggest fckng mistake ever), it hurt SO BAD. I just remember saying "OW" reaally loudly. Anyways, he basically asked me if it was ok and I told him it was really painful so he took it out and we did other stuff. I was so paranoid that there was shit on his dick when he pulled out. So yeah, that's my anal experience.
