Sex with my girlfriend lasts only 30 seconds and I am terrified she will leave me

DEAR DEIDRE: I CAN’T last longer than 30 seconds during sex with my girlfriend.

We’re both 25 and have been together for five years.

We’ve always had a good, sex life, but recently my performance has been shocking.

I have such intense orgasms that I just can’t hold back, but it’s beginning to affect our relationship.

My girlfriend gets next to no pleasure, and no matter what I do, I cannot last.

She’s beginning to feel that the intimacy in our relationship is gone...
