I'm new to the forum, in fact this is my first post, but I'm not new to out of the ordinary sexual practices as well as sexually oriented forums.
As a young boy to younger man I always new something was different about me than everyone around me expected me to be. In my early teens I started experimenting on my own with what i thought was highly unusual behavior. I started by shaving my legs and pubic area at about 12 (not much hair to remove at the time) but I saw my mom shaving in the shower (very close to mom growing up) and then moved on to the feeling of sexy women's underwear. After a year or two I started coming up with new ways to stimulate my mind which becomes bored easily. Tried urethral sounding with random household objects, writing pens, knitting needles, framing nails and anything else that seemed viable.
For a long time I hid this part of myself from almost everyone. In my late teens I had what some may consider a traumatic encounter where someone tried to strangle me. At that point I came to a dramatic realization (for a 17 year old I suppose) I can't control anyone or anything around me, only myself and my own actions and choices. So I was going to be me, people could accept it, label me or bugger off. Since then I've come to realize it's often simplest to allow some people to make assumptions about me and move on. When people ask me about my sexuality my typical answer is I'm Bi, but that's such a gross oversimplification of a incredibly complex machine. For people who I care to explain it to, I'm "Sexual", if an action, activity or fanstasy brings me sexual or psychological pleasure or comfort I'm more than willing to give it a shot. If I enjoy it as much as I thought I would, I'll keep doing it; if I don't, well I know for next time.
To answer the original question though. Reading forums and other men's experiences as certainly influenced my sexuality and help me accept even more about myself and my nature.
I'm really looking forward to being a part of this unique community. If anyone is near corvallis Oregon USA I'd love to hear from you. I'm only just starting my ball stretching journey and I'd love to hear from you and learn from your experience
