Difficulties (potentially long?)

So, I've been comfortable with being bisexual for quite a while now. However, due to circumstances, I've mostly wound up dating/being with women, with the occasional guy here and there. At the moment, I find myself in a situation to be looking for my first boyfriend/regular gay sexual relationship. I don't think I'm fat, personally. A bit of a gut, sure, but mostly broad shoulders and muscular back/legs/etc. I met up with a guy and he opened the door, took one look at me, said "no, this isn't going to work", and proceeded to text me accusing of faking my pictures on the personal ad I posted (I didn't, obviously). I feel really shitty and it makes me not want to do anything with any guys if they're going to be that superficial. He also told me not to post as "Average" and to not lie. Thoughts?
