i have a boyfriend but i imagine myself with a girl all the time

There are several possibilities as to why you do this.

1 - Instead of being turned on by the girl on girl you are turned on by the type of sex or foreplay that they are doing

2 - Maybe you could be turn out bisexual, it isn't a bad thing

3 - Your boyfriend isn't satisfying you and so your body is trying to find a new source of sexual pleasure.

Of course it could be something else but i would say that these are the biggest possibilities. I really hope that this is helpful - let me know. xx

I love watching porn and has tried sticking everything i could into my vagina and it always feels good. But i know i love being with girls. For u i think u just need to try it out with a girl and see how things go for the time being
