5in is average size, it’s not that small. Just imagine if it was only 3in now how would you feel? But about women and they’re ideal size.I Would think that technique would be a big role and also if your average size then you shouldn’t have a problem. Anything below say 4in is just not going to go in, it would only fit about 2in in the vagina and what woman would be happy with that? So yea 5/5.2in is fine!
