I find that there are 2 types of ED

Those who show zero sign of getting hard in the first 5 mins - they never get there and never cum. Oral won't work and I avoid it.

If there is sign of a semi erection in the first 5 mins, I see it as a challenge and part of the service to get them hard but like others I can't stand sucking or even touching a soft cock (maybe to do with working in care home in the past!) A good way (other than oral which is probably the best way) I have found is to ask to see how they wank and get them to stimulate themselves - once hard they are on their way to ejaculating providing that you go at the right pace. They wont stay hard for more than 5 minutes so you need to get them over the edge without rushing. Dirty talk as they stimulate themselves is good for that. Rushing into intercourse can send them soft again and lead to them going home without having cum and disappointed.

I have quite a few ED clients and they enjoy cumming more than oral or f***ing

I once had a man who had some sort of operation which made him have the feeling of cumming but not actually cumming?? Didn’t tell me this until after!!!! Which meant I had no cum rest the whole time lol..

Orgasm and ejaculation are two separate processes in men. They usually happen at the same time, but men can orgasm without ejaculating and ejaculate without orgasm.

Some can control this, the large majority can't, a few - as here - don't get the choice.
