You could benefit from a lifting routine.

I suppose appearance may create sort of a shunting effect [on the sexual perception metric] so that it would be critical to have muscle mass at like 100% of normal rather than like 30% that I have now. All of my personality efforts are being multiplied by 0.3. Then at about 120% it's a bit better, and getting higher would eventually lead to diminishing returns on the time investment.
