So this girl im dating (basically g/f) and I were talking about sexual experiences, and we got into the talk of oral sex. She claims she's never had an orgasm through penetration (which is understandable), and she even has trouble w/ oral sex, and only one guy (long term b/f) has ever made her orgasm. She even went on to say that it would take him 25 mins to get her to cum. Now my question is, is this normal ? I've never been w/ a girl that took that long to cum. Maybe the fact that she's only 19 and limited w/ experiences, but i dunno.....any thoughts ? I know how to locate the g-spot and provide sufficient clitoral stimulation, and blah blah. THink i'll have trouble as the previous guy or if i know what i'm doing i'll get her to cum in less ?
