Unfortunately my marriage partner of 51 years has never allowed enemas, anal sex or any form of anal play, giving or receiving. Of course, apart from unsuccessfully trying to discuss the issue there is no question of my forcing or even accepting unwilling participation. On other counts our intimate life is really very good.
I have to confess however to being in touch with a willing F enemate on a two way no fee basis and also a paid WG (In the UK, a 'Working Girl') who gives and sometimes receives. Almost always and with both ladies enemas form part of a full sexual session involving anal intercourse, dildo and finger play.
I have to say I consider myself incredibly fortunate, especially at my age. I have also to regret that my dalliances with the ladies is a secret and I suppose that is a betrayal of the marriage. That being said, I am never questioned when I 'go missing' and it may be that it is assumed that I am 'playing away from home', though it may be thought in a different format to the truth! A caution though to those who 'play away', especially with a WG. I get a standard STD check, usually a couple of days after each exposure and do not engage in marital relations till I get the all clear. It's free to get checked on our National Health Service. The drawback is sitting in the waiting room with all the young people! At least the system will allow you to be anonymous. I get a number to use instead of my name.
It might be asked why, when I suspect my wife knows I might be 'playing away', I don't 'come clean'. Well, she may not know or suspect and 51 years is a long time to risk!
