can't orgasm

I would suggest seeking medical advice from a professional.

Maybe you have cowardly sperm who are afraid of the vaginas defences.

What you need are some brave premature ejaculators who cant wait to get in there!!.

Dave will explain.

My opinion is 'so what?' And I am not saying that in order to be obnoxious. The lady can be manually satisfied and she should be above having to have your organ orgasm. There is more to life and marriage than sex. Maybe you two should commence understanding that.

I am gay. Even when I am with someone who is really sexy, oftentimes I get flaccid, and quickly. The penis has a mind of its own. At 72, I say 'so what?'. I do masturbate and too often this is a reason for not being able to perform 'in person'. The fantasy subsides when the flesh is present. And, finally, 'so what?'. - David Lyga

So see a doctor - obviously no one here is an expert and we can't help you. All the best.
