Recently I had surgery done with a long standing issue and returning to work I can’t offer sex for 12 months so only doing oral services.
Today been my first day back. Was wondering if anybody else has done this and managed to do okay with not offering sex?

At least 50% of my bookings don't involve penetration.

I'd suggest aiming your ads at an older demographic (since with age often comes ED) and sell it as a "no pressure stress reliever" - make a feature of the fact that there's no performance expectation for them.

I have been in situations where I could not do full sex - mainly to do with thrush, chlamydia (being responsible until the meds were finished), BV and periods. I found that it was best to do a long run of no intercourse rather than switching from one week or month to the next - otherwise clients got confused.

I did a big "marketing" drive to big up the keeping my pants on offerings. Business did drop off a bit but I got new clients who really enjoyed what I offered. They tended to be older and more civilised if I'm honest. I learnt some proper non-sexula massage techniques too.

My advice for the appointment is to wear jeans and keep them on or if you wear a skirt, thick tights and big tight knickers to stop hands wandering or misinterpreted visual signals that give ideas that things might progress in the downstairs department. If you have bare legs or stockings/knickers on show, the wandering hands have a habit of seeking out the closed shop.
