So your point is that maybe you don't really know unless you try. And that's totally valid. But I think that sometimes for sexuality one does know before trying. You can know beyond a shadow of a doubt that you are not interested in men. Or not interested in women. I do wholly agree, though, that experimenting with various kinds of sexual stimulation and pleasure is a great idea. You may find that you really enjoy something that you hadn't given any thought to before. I think that's what you're saying, yes? That you should experiment with various types of pleasure and not necessarily different genders (unless you so desire). That said, I would not enjoy vomit-play. I know that.
