he never been able to cum inside

my boyfriend is 47years old, also he is a workaholic , he works in the financial field. Anyway . he never been able to cum inside on any woman , he is been with 5 women in his life (so he said) he seems very introverted , we do have great sex...but he can't cum , he just stop when he is exhausted. I want to help him out , I do feel bad ,I wish i can make him feel the same way he makes me feel . I try ,but I got tired most of time because takes an hour or more. He confess me he does have a porno addiction , but so is every man I ever know .I even watch a porno movie with him (once) see if that would it help , but did not. he lost his virginity in his 30's....I do like him alot , but feel bad too , is like some part of me does not feel complete if i don't make him cum, does that makes any sense ? Plus will be great to be the first one and be a turn on the sperm part :P
i try books , talk ...but no sure what else .how unusual this can be ? I have more question and logic is not longer there for me . it does bother me .so I do wonder now who needs help :(

If he's really that great a guy, stick with him.

Over time, he may retrain himself to climax with you, if not inside you.

He's admitted that he's got a porn addiction. He may have trained himself to only respond to that type of mental stimulation.

But, don't feel like his problem is your fault. You can be there and be understanding and supportive, but it's HIS problem. HE has to work it out.

You can't do it for him.

If you like, you can offer to go to couple's counseling with him, if he wants. You can go seek medical help, if you like.

But, many women appreciate a man who is long lasting, but an hour may just be too much. I'll bet that he's jacking off and that's where his energy and sensitivity to stimulation is going.

If he would knock it off for two weeks, and then try intercourse with you, I'll bet he'd come in record time.

PS: If he's a workaholic, he may be putting all his energy into that instead of sex. Think about it.
