Don't Know If I'm Gay Or Bi Or What

I've got a girlfriend, we have made out a lot, I've felt her up, sucked on her big titties, stuck my hand down the back of her panties and played with her incredible ass, and only felt her between her legs over her jeans. I did get her while in a bikini during the summer to pull them aside and show me her pussy but couldn't touch it.

Last night I was with a man helping him at his house doing repairs. It went late and I stayed over. With some pot and some beer, I ended up getting fucked, I also sucked him and he sucked me. I'd never had another person make me cum before and the BJ felt great. I knew, even when he was blowing me, I was going to get fucked. His cock was to me, huge. He said it was 9" long and I have no doubt on that. But it was really, really thick. Almost 2 inches thick, he had taken his time in using fingers and plenty of lube to get me opened before he fucked me. It hurt but I wanted him to do it. I let him kiss me like I kiss my girlfriend, he played with my nipples and sucked on them the same way I do my girls tits. He picked up his speed, and then jabbed it all the way into my butthole, pulled out and jammed it in again. He was shooting inside me. He kissed me long and deep before he pulled out. This morning he fucked me again, and gave me a blowjob again.

I am about ready to pick up my girlfriend and go to the movies. I still feel the soreness in my butthole from his cock stretching me open. I actually miss the cock pushing and shooting into me, but I want more than ever to push and shoot into my girlfriend. I want to fuck her tonight, no matter what. I need to know which I like better. I will fuck her tonight no matter what. My perfect fantasy is to fuck her, and go to his place and get fucked again.
