My husband insists that men can only physically go on with no sex (or masturbation) for a maximum of 3 days. Is this true?

Not true. My hubby is a less active than me. He prefers once every week or two weeks. I used to be very sceptical about this. But really he doesn’t have the tendency to want sex so often. So even if I ask for sex, sometimes I’ll get rejected. We cannot force our partners to want to have sex - and vice versa.
