Im not a guy either, but I am also a lesbian.
In a girl I actually like the really skinny girls, that most people say is to skinny for them. I like boney girls. Im not a fan of reallyyyy fit girls though, I dont want to see your stomach muscles while your standing there, it grosses me out. Now if you flex your muscles to see them that ok.
i dont like really fat girls though, Ive dated a couple, but we never had sex, and no its not because they was fat. One girl we hadnt been talking long. Another when I started to stay with this girl everynight almost I noticed she didnt shower, yuck!
But I do find pregnant girls hot. I always have. I actually have a ex who I was with for 2 years, met her while she was prego, she left her gf for me. And she also got prego again with me trying to have us a girl. It got a bit crammed in the shower Lol, but I found her more attractive pregnant than I did skinny.
I have a thing where girls I like cant be any bigger than I am. Of course Im not super skinny, im 120 pounds, muffin top and kinda big arms, and I think my thighs are big also. The weight of the girls can be more than mine, its about how big they look. Of course I dont ignore bigger girls, I try to get to know them at least, and if we click than good, if not we can be friends. I dont want a girl who starves them self though, she needs to eat lol
