Can you become a virgin again? At least mentally?

I'm 37, lost my virginity at 19.

With the exception of a "get it over with" sexual experience that involved money, I have only been with one woman (my ex wife) in my life.

I have been into chastity since I was a teenager and stumbled across Altarboy's site while searching around for self bondage information.

My wife and I were kinky from the start and I always fantasized about what it would have been like if she had just been a little bit kinkier and we had jumped into the Femdom and chastity stuff earlier and I had never been allowed to have sex with her.

We played with chastity and denial through our whole marriage. The last number of years I was cut off from penetrative sex entirely.

Since December 27th, 2009, (~6.5 years) I have only had sexual intercourse a single time, and that was just over 3 years ago.

The relationship I had with my wife ended (on good terms) so the last time I have had any type of sexual interaction with another person was April 2014.

I am finally looking at starting to date again, and find myself much more comfortable with my kink etc and the idea of starting a relationship in a D/s context is very appealing.

I've seen some threads in the forums about being made to be chaste while still a virgin and I have always thought that idea was incredibly hot.

So that got me to thinking. I had once heard that the cells in your body fully regenerate every 7-10 years, so that seemed like a great number, but a token amount of research explains that that's bogus.

But it leaves me wondering about maybe there isn't such a thing as becoming a physical virgin again (of course it's not like we have hymens etc anyway) but maybe it's more about the mental aspect.

When I had that one off sexual encounter, it had been about 3.5 years since I had been allowed to have intercourse. For quite a while before it happened (it was oddly a bit impromptu) I can honestly say that I had reached a point where I was really having a hard time remembering what it felt like to be inside of a woman. Experiencing it again, really felt like the first time to me. It was overwhelming and incredible. (and over in a about a minute, much like my actual first time)

It's now been over 3 years since that one-off experience and 2 years since any sexual activity at all.

I kind of feel like I'm back to square one in a lot of senses sexually.

I'm really curious what others think. Is it possible to go so long without intercourse that at the very least "mentally" you become almost virginal?

I really can't remember what intercourse was like....
