My only issue with fat girls is when they can’t restrain their own insecurity. I am seriously attracted to confident and smart women. After that, real attraction is when you can confidently, and with a confident partner, find what is fun and stimulating for you both.
Fat should NEVER be an issue. That a girl likes slow and comfortable sex with a lot of kissing and reassurance? Or that some women like quick, impersonal, a directed purpose, and functional? THAT is what’s important: When two people can relate to who they really are. And share that relating, whether through casual, recreational sex or in the context of true love.
(Note on context: I used to be very fat myself and still bear insecurities from it. On the other hand, I carry the compassion in my heart that kind people gave to me at a time when I needed it.)
