I knew I was into this from a young age, but grappled with conservative values drilled into me about fidelity etc. And I hate being cheated on to this day, it still makes my blood boil. Had a few relationships that ended badly that way. I also tried swinging sites but again had some bad experiences.
However, I had one relationship that was different. I can't remember how it came about but very early on we had a frank and open conversation about sexual fantasies and swinging was mentioned, along with fantasies about group sex and having sex in front of others. We were pretty much on the same page, so we decided to explore and I still can't believe how relaxed I was about it. We started very simply with some cam sessions for others and after a short while connected with a couple in Canada. We cammed fairly often with them. We talked about getting together but in reality when you're on opposite sides of the planet, it's really just talk, isn't it?
Later, we discussed seeing others and we set out some ground rules (mostly to settle my nerves), which included full disclosure. It actually worked to improve our sex life, because we could share tips on what another man/woman did that turned us on. We didn't really get around to having anyone join us except one time.
She had blindfolded me and was giving me a birthday blowjob, which sounds kind of ironic because she used to suck me off at every given opportunity. Then, there was a knock at the front door, so she got up to answer, despite my protestations about neglecting me etc. I heard her coming back, so I asked who it was and she said it was her friend Jo. I thought nothing of it as I felt her lips around my cock again. Then a few moments later I felt someone else sit down and press up against me. My gf leaned in, nibbled and breathed in my ear (which used to make me so hot for her), whispering: how do you like your birthday blowjob, dear?
It took a second or two for my mind to click and realise it was Jo's lips around my cock. I exploded in her mouth almost right away. The start of an experience I won't forget in a hurry.
Generally, over the years, I've found people active in this lifestyle to be much more open about their kinks and less judgmental. We are all built differently and it is interesting to see what it is people are into. Happy to be here and mingle. DM me if you want to chat or know more.
