females: have you ever orgasmed during penal penetration?

[sexhead]

if you have, what made that extra oomf to make you climax during penal penetration? my girl claims i'm the only whos ever made her climax with my dick, but it wasn't from actually insertion but rather rubbing the tip of my penis all over her vagina.

i may have been close to making her orgasm while sex, but either my endurance failed me or i cummed before that could happen. i REALLY wanna make my gf climax while i'm fucking her. she says she cums ALOT but can only climax when she masturbates.

need tips!
