This subject found that while the orgasms were extremely enjoyable at the time, he could easily spend too much time experiencing them. Further, he had an old neck injury which flared up in association with some neck spasm at orgasm whilst lying prone. It has proved difficult to stop experiencing these orgasms and ‘unwire’ himself back to normal.
Eventually, the man figured he should go back to masturbating and having regular sex. He still had up to 10 non-stimulatory orgasms before ejaculating during these encounters, but was able to stop having these random orgasms for a few months at a time.
So you be the judge. I know plenty of men, me included that have a fear of anything going IN back there, I’ve always gone by the “exit only” pledge. But to each their own.
In my opinion, the main problem I see that arises if a man has to “re-wire” or “convince” himself to like it. No one should have to convince you to do anything sexually. If you like you like it. If you don’t, you don’t.
