Chastity and orgasm denial discussion

I’m 37 years old and lost my virginity at age 19. Apart from one transactional sexual encounter that was more about getting it done, I have only ever been with a single partner (my former wife) throughout my life. Chastity has appealed to me since my teens, and I found Altarboy’s website while looking into self bondage resources. My ex-wife and I were kinky from the beginning. I often wondered what would have happened if she had embraced kink more fully earlier on, leading us into Femdom and chastity where I never got to sleep with her. We explored denial and chastity throughout our marriage together. In recent years, penetrative sex was completely cut off for me. Since December 27th, 2009 (roughly 6.5 years), I’ve only had sexual intercourse once, which occurred just over three years ago. The relationship with my wife concluded amicably, so April 2014 marks the last time I engaged in any form of sexual interaction. I am now ready to start dating again and feel much more confident about my kink. The prospect of entering a D/s dynamic is very attractive. I’ve read forum threads discussing men remaining chaste while technically still virgins, an idea I always found incredibly appealing. This prompted some thought on my part. I recall hearing that the body’s cells fully regenerate every 7 to 10 years—a figure that seemed reasonable—but further research suggests this is not entirely accurate. Still, it makes me wonder if true physical virginity might be unattainable (hymens aside), but perhaps mental virginity is possible instead. That single sexual encounter happened about 3.5 years after my last one. Looking back at the period leading up to that somewhat impromptu event, I truly believe I had reached a point where it became difficult to recall what being inside a woman felt like. Experiencing it again was overwhelming and wonderful (and finished in roughly a minute, much like my actual first time). It has been over three years since that one-off experience and two years since any sexual activity whatsoever. Sexually speaking, I feel as though I am back to square one in many ways. I’m very curious about your opinions. Is it possible to abstain from intercourse for so long that you become virtually “virginal” in mind? Honestly, I can’t quite remember what intercourse feels like anymore…
