My husband didnt ejaculate when we had sex and most of the time it softens after a while?? his work is very tiring and he's overweight is this a prob?

This is a case: of extreme Delayed Ejaculation. It almost always has a psychological component; may also be physical. Important question is whether there is no ejaculation in all circumstances, ? also occurs with masturbation. If so, then more likely to be physical including alcohol overuse, medication side effects. Or pudendal (perineal) nerve compression. Needs eval by professional of psych/physical causes.
