I'm ashamed

I don't think it's "common". I also don't think you should feel ashamed about having any kind of fantasy.

I have been the center of gang bangs twice. It took years of fantasizing and discussions, it took years of lots and lots of other very adventurous sexual experiences before my bf and I were actually really ready to consider trying to make it happen. Even after all of that, logistically it was impossible for us to pull off in the small town we lived in.

Both times it happened we were traveling. And the opportunity presented itself to us. If we both weren't ready for it psychologically and emotionally there's no way I would have just been able to spontaneously go for it.

The first time was 5 gentlemen plus my boyfriend. The second time was 3 gentleman plus my boyfriend. We LOVED it! If you go through with it I hope it's under the right circumstances and you have nothing but fun

I acted on an urge with a very taboo aged sex partner that I had befriended. I was gentle and used Vaseline to achieve anal penetration and ejaculation. I lived in nervous fear of being discovered had the parents been told. It's been decades and I have moved three times so nothing has happened. I keep my play only online at cam to cam sites.

If you are in a boring marriage, its common to have such thoughts. Go buy yourself a big toy before you act upon this filth.
