My wife is pretty small 5'4" 120lbs 36c. However I've had a few a little bit more petite. All are white and I'm a black male. Yes I love intelligent attractive white women but thats a different story... I love small girls not sure that penis size diff plays a part or not. Here is a rundown of my expierences.
One was like 5'0" and 90 lbs max. She had a nice round butt and ample tits. She would come over after school and we would have sex daily. I had to work it in but she wasn't the tightest Ive had. I don't think she liked the sex too much because I hurt her and she paid me back. She told my cousin who was her best friend at the time that i had a really big penis. Great lol...
Another girl I had had 2 kids and was super thin but probably 5'3, she loved my dick. Said she loved the way it filled her up. She would keep coming back for more day after day and just constantly tell me how she liked my size.
Another girl I was with wsas 5'1" and super skinny she had 2 kids but when we had sex she was so vocal she came easily and was convulsing for like 5-10 minutes straight upon entry. I really filled her up good.
Another was 5'0 max with huge tits probably 100lbs she was the tightest I've had. It was so tight, it was hard to get in and when i did it hurt me during sex. It was okay I just didn't like it being too tight. Too tight isnt good either
One girl was 5'1 and maybe 90 lbs she was so good but i hurt her during sex and she didn't like that too much. However, she did "stay in contact" after that initial act.
The shortest girl ive had was probably 4'10 but her butt and boobs were perfect. i will never forget her because we put a hole in her apartment wall while screwing. I was doing her doggy and she said "you trying to hurt this pussy you can't hurt this pussy" wow... The best line of my sex life.
My wife on the other hand has the best pussy I've had, hers grips me when i push it really deep. You can feel it enter the fornix and it just grips my head, mmm.. However, she wont let me do her doggy, or legs up because she has mentioned I have a long penis.
anyway i hope my experiences helps to answer your question
