It doesn't sound like you're a lesbian or anything, and even though you have these dreams about women etc it doesn't mean you are. Maybe you don't think a man having sex with a woman is disrespectful; maybe it's the situation when you see it. Or you might just have a bit of a fear about sex and allowing aomeone complete access to your body. As Eiri said before, it could be that you recieved bad influences about sex, that maybe made you feel it was wrong or dirty. I know how that feels, I was always told (primarily by my dad) not to let guys touch me, bad things will happen etc and now I can't even enjoy sex because it causes me pain, and I think this one of the reasons why.
JUst remember that sex isn't 'wrong' whether it's man/woman man/man woman/woman or whatever. It's only disrespectful if it is done against a partner's wishes.
Gordon Ramsay eh? Not someone I've dreamt of myself lol but I can sort of see why you would! lol
