I would prefer to be slim, long dark hair, high cheekbones, wider hips, no brow ridge, no bodily hair except for my pubes and head hair and maybe slightly bigger eyes. As for genitals, I think I would prefer to have female breasts and a working female reproductive system.
Reading the above is strange, because I'm OK with my male body and don't believe myself to be a transwoman. However, I wouldn't miss it if I suddenly changed into a female-bodied person (as long as I was accepted as a woman as if I had always been one).
However, if I stayed in a male body, I would just have the above except with shorter hair, no breasts and a working male reproductive system. I wouldn't want to be muscular at all, but maybe just slightly toned.
