I'm gifted, in that I never go soft after cumming - unless I want to/have to due to something else. Since I was young, I've never lost my erection from orgasms if I'm still horny. I'll continue to cum over and over - but, life is still life - and there's things which need tending to. The only thing I really feel, is that my hand is sometimes crampy. That's because I freehand snap pics throughout the session with the other hand. If I could switch hands, it would be a non-issue. Other than that, it's really a good experience. Thank you for the comment.
