i get aroused by muscular women.
Sex, as with every other woman, will very much depend on how you treat her and how the chemistry will blend in between the 2 (or more - lol) parties involved.
The few times i had the opportiunity to have sex with fit/muscular girls have been very nice, but again i had great times with non muscular chicks alike.
Still, banging a hardbody is above climax - it s heaven
