It's a massively subjective question. What is a "normal" sex life, what was your sex life before punting, what is it now, what do you get from punting that you don't or can't from a civvy relationship, etc.
I think a "normal sex life" is probably massively overrated, in the respect that the average bloke's experience of sex is characterised more by famine than feast. The average guy goes a long time without sex, either between relationships, or when the honeymoon period ends. The average guy spends most of his time frustrated, envious, and distracted. Quite possibly resentful of his wife who's turned from a hot young nympho into a frigid fat cow in the space of five years and two kids. Of course this isn't everyone's experience and some guys are lucky enough to have sex on tap with a partner who matches their libido, but that's rare. I'm confident in saying that the average bloke in the office, down the pub, whatever, isn't getting the frequency or variety of sex he wishes he could have.
In that respect I'm happy to have an arguably dysfunctional sex life of paid experiences with strangers. It's no substitute for genuine human connection of course, but it's a great pressure release valve.
