My introduction to anal sex was from the most unlikely source.
Not through porn or SPs, but a suggestion out of the blue from my very demur OH.
We'd known each other since our teens and when we married I realised that her interest in sex was mainly limited to straight foward sexual intercourse.
She didn't like oral or fingering etc which I assumed was a result of a strict Catholic upbringing and education at a private convent school.
After having to attend pre marital instructions from some dodgy old priest, we followed the teachings of the church and relied on the 'rhythm method' of birth control.
We must have been using the cha cha rhythm instead of the bosa nova, as in a very short time babies inexplicably started to appear.
Then after being together for many years, one night she suggested we try anal sex.
I don't think she would have got the idea from Sister Ignatius at the convent of from the priest at confession, so maybe my suspicions about the milkman were correct.
How could I refuse. It required a lot of care and patience until we were able to find the best way of performing it comfortably, but after a while, we both found we enjoyed the sensations more than vaginal sex. Despite what others may say, after having a lot of children, her vagina wasn't as tight whereas her anus was.
She also achieved much more intense orgasms with the help of clitoral stimulation.
Eventually with a combination of menopause and my wife's poor health, our sex life was reduced to an occasional handjob, so I was easily tempted into an occasional affairs.
I'd had the odd one night stand when working away, and for whatever reason each of my affairs were as a result of women approaching me, sometimes through work connections.
The three affairs that lasted a few months were with women who were younger than me and much more sexually experienced and liberated. They introduced me to things I could only fantasize about before.
Each of them enjoyed anal sex, all at their request.
In fact the lady I had my last affair with about 30 years ago surprised me on about the third time we had intercourse I suggested we might try anal sex, she said you're already there.
She loved anal sex and I can only assume she'd had years of practice as she didn't even require lube, just a bit of spit on my dick or the lubrication from her vagina.
That affair ended badly and not surprisingly nearly destroyed my marriage.
It was probably inevitable I would eventually turn to SPs.
Then experiencing anal sex with some of the real aficionados like the legendary Chelsea in Manchester, made me realise that everyone's different in their sexual tastes and preferences.
The overriding consideration is consent, consideration and communication between all participants.
