Sex advice with Suzi Godson: My younger lover is disappointing in bed

Q: I’m in my 40s, and I’ve started dating a man in his 20s. We’re having a wonderful time — but sadly not in bed. When we start to have sex there are no problems at all, but he quickly loses his erection during intercourse. He drinks quite a lot and occasionally smokes cannabis. I wonder if these have an effect in the bedroom

A: People who smoke cigarettes are more likely to develop erectile dysfunction because smoking damages the vessels that supply blood to the penis. Smoking cannabis only makes it worse.
