I am in excellent shape and my Gyn says my vagina is of normal size.It is my hubby's huge size compounded by a pronounced upward erection curvature and his foreskin on top.He is uncircumcised and his foreskin rolls down from the top while inside of me and forms a protruding hard rigid lip below his top.It is that lip and his erection curvature that locks him in tight for hours.Sometimes I get sore but no pain at all all pure pleasure excep for being stuck. Prefer if you email me at Dennyoooo@webtv.net Love.
