Something being disgusting to you should not be the problem of the people who are doing the thing itself - think of it as some food you really don't like.... should it be banned in some way?
I mean, I don't like some type of girls (no need to be specific) I mean, literally the idea of sleeping with them disgust me... I know for a fact that many guys find these same girls pretty exciting... sexual attraction is like that, there is a whole scale that goes from disgust, to neutral all the way to I can't hold myself, and what does what to who is very much an individual thing, wether the source of a particular attraction is social or purely genetic is of little importance.
Either way, it's really not more complicated than that, some people just like to put their nose in stuff that isn't their business.
On a lighter note, keep in mind that all those guys that prefer other guys are a lot less likely to be interested in the girl you like in the future, so be thankful!
