Crop Tops Make Me Weak

I can't handle seeing a woman's bellybutton. It's not JUST the bellybutton, it's the curves around her waist and hips, the curve on her back. Seeing a girl in a crop top, sports bra, bikini, or just a sliver of skin from their midriff makes me WEAK. It's really hard to walk around in the summertime. Are women aware of this? Do other men feel this? I almost only masturbate to photos of women in crop tops.
