what types of girls are you not physically attracted to?
for me it would probably have to be small women in general. i've dated a few girls who were well into their 20s but they had the bodies of young teenagers and looked very young.
one of the few incidents where i wasn't able to obtain a full erection was when i was with these types of girls, my body was just saying no. they just aren't my cup of tea. funny cause i know some guys who absolutely LOVE these types of girls.
