The truth is girls have way more options than guys and girls aren't going to choose the worst option.
But still 30 is still young. (I actually can't believe how far away and old 30 once felt). But look after yourself and be nice to be around. Someone will touch your peepee.
dunno I've seen some visually mismatched (by social/tv media standards) couples. The fat white weeabo man with the cutesy japanese girlfriend exists, I've seen him and he's huge yet somehow absolutely terrifyingly good at ddr/itg. The man defies gravity on those no bar cardio tracks. There are others too but this man is a legend at the arcade I frequented in highschool. Actually I've has suspicions that he is just fat looking, but actually rock solid if you were to poke his belly. In hindsight probably not the worst option...
There is maybe a subtle but big difference between being a fat slob and being powerful.
Big guys/ strong guys always seemed to be attractive at least to some people. Henry the 8th was big to look good. Apparently he was much slimmer as a youth.
But I'm not a woman and I have no first hand experience on being overweight so what do I know?
