honestly, a there is no standard answer for this. If a guy likes you, he likes you. If he doesn't he doesn't. Its the same as women right? How many of your girlfriend have dated guys you wouldn't particular date yourself? Probably many. Why? Because everyone has different characteristics they find appealing. Its about how the two of you work together.
I would. I have and have no problem with them. I will actually take a bigger girl before I take a skinny girl. I used to have ick issues with larger women but only because I didn't see any as gorgeous as you or some of the other big girls I have seen since the time of my enlightenment. Other guys are scared of not being attracted to one, being embarrassed to be in public etc..
