About 10 years ago, before I met my current wife and after my ex-fiance left me for another guy, there was a about a 6 month period of being single. Typically I had no success at all with casual sex/ flings with any women and relied solely on masturbation, porn/ adult book stores and in the end met up with a 50yo dominant, well hung male i'd chatted to online (yes, i'm bi and no, he was white). We 'dated' exclusively for about 6 weeks and in that time I was what most would describe as his 'bitch'. We had sex every single day and sometimes twice a day.
It got to the point where I couldn't go even a few hours without thinking about him or contacting him. I was like a puppet on a string for him....I had waited all my adult life to experience this, and I just wanted more and more. Anything he wanted, or wanted to see, was done without any hesitation...as a submissive cuck, I just wanted to worship and please him over and over again.
It was the most liberating thing I think i'd ever done up to that point. I think I realised, as a single cuckold/sissy here was my opportunity to live out all my fantasies i'd had since a teen. Also knowing once I met a new woman, that window of opportunity will close again.
I would say, if you have this moment in your life, experience all you can... especially while you have a supporting ex and before you meet another woman who may not see things the same as you.
