my partner and I don't watch porn at all. I am straight, but I will say, I have had fun with other girls back in the day when we were young teens! I am straight like I said, but it was a fun little thing to do back then. I never actually got turned on or had any feelings for my girlfriends, but something about it was very fun. Lol. When we were in high school, it was very common for girls to kiss & often do more and still be straight. Every female in my circle of friends at least kissed another girl. I must say though, I think one of the main reasons it caught on was because a lot of girls think it's attractive and they do it to get attention from men. I had one girlfriend who wanted to kiss everytime a male she liked was around. It got kind of old though. She was always rubbing on us & kissing to turn on the men. Lol. It's just not worth it to do all that just for a little attention.
Anyways, my point was, I do think you can be straight and still enjoy the same sex in some way.
