Am I too big?

I'm currently at my heaviest, 172lbs and I'm 5'5" tall, pants size 10/12, shirts M/L. I get a good amount of attention from guys, but I work in a bar... so, beer goggles.... I feel like nobody would find me attractive/as attractive when they're sober... Am I too big for guys to date or am I crazy? I feel like I would crush a guy if he was any smaller than me and I got on top, and the guy that's been talking to me is maybe 120-130lbs soaking wet, so I'm trying to keep my distance.
