I’ve always been straight and never really thought about other men in a sexual way. But recently I was at a friends house and we were all getting ready to go swimming and started to get changed. We are super super close so I’ve seen both of them naked before M&F. But this time when he took his underwear off to put on trunks and she did the same I caught myself looking at him and getting aroused. He noticed and smirked at me, make it way worse. When we got done swimming we all were getting cleaned up and changed, when he walked by he asked if I liked his “BBC” I made a joke and we went on for a few weeks like nothing happened. A few weeks later we all went out with some friends and got pretty tipsy, we all went back to their house to keep drinking and there was only 3 of us left. After she went up stairs he asked me if I wanted to touch it instead of staring. I was shocked and kind of froze, so he grabbed my hand and put it on his penis. It felt strange at first but started feeling better the longer it sat there. He then took his pants of and I finished the job with a blow job. I thought it was just me being drunk, but now I find myself looking at certain types of men. Ultimately I think this will ruin my friendship because he keeps asking for more and I don’t want to. Thoughts?
