Are there women who like to masturbate to lesbian porn who are not lesbians?

Other than bisexual women, there are a few "straight" women, though you're unlikely to find any because they are (usually) secretly curious or in denial.

Im sure there is because a girl dose not have to be gay to be turned on by certaint things. she could just like having a 3rd part once in a while or find other thigs sexy. But i would say that if she finds other girlks a turn on maby she should try it out to see. if she likes it better. you never know.

Most likely. Some people just get a kick out of being naughty and occasionally doing things that are different (sexually). They often get bored with the usual. Sometimes it may turn a woman on to think of how a man would react to the scene. For some people a naked body is sensual no matter what because sex is sex & any kind of sex may turn them on.

Oh, and I forgot to say that if that is ALL that the woman watches, I would definitely think something is up, but if it's just sometimes, maybe not.
