Advice: More Trouble Cumming

Q:
I am going through a divorce where she left me for another woman stating that we got married too young. We were married for 29 years. In that time we had a very inadequate sex life due to her issues with weight. My question is that now I have a girlfriend and I really please her. She can' believe That I can keep it
hard for hours and can go all weekend. The problem is that I don't cum and this has never been a problem before. I do ejaculate when I masturbate however. Any suggestions?
