Easier rejection: Straight or Gay girls?

When is it easier to deal with rejection, when it's from a straight girl or a gay girl?

I tend to take it easier when the girl is straight. If she wants a guy, I can't be a guy for her and have no desire to be so. When it's a gay girl my feminity (or lack there of according to my crush... who is gay) feels more threatened. It's like "why am I not woman enough" if that makes any sense.
