<human>: Hi, I'm looking for advice here. I'm in a moral dilemma of sorts. A short context:

I lost my virginity to my current girlfriend (been together 6 years, I'm now 30), rather late... 24 years old. Until that point I'd never been with another woman... not because I'm ugly or unpleasant... but mainly because I've always just been way too shy. I was embarrassed, and to this day she doesn't know that I was a virgin at the time (luckily I'd done enough reading to be decent enough in bed. Improved since, of course.). I really love her, and can foresee us being together forever. She does as well, and we talk of getting married.

There's a hitch, a problem, in my mind though. I really, desperately want to know what it's like to be touched by another woman. I get all the emotional fulfillment I need in my relationship.

We're currently in a long distance relationship (different continents, I only see her twice a year). We'll be moving back to a normal relationship midway through next year. I have the opportunity to have sex with a person who I know is clean, who is not a friend, and I will only see once in my life. I don't even want full sex necessarily... just even intimate touch or foreplay. I know I can do this and my gf would never know (it would literally be impossible, unless I told her). The desire for this experience is so strong, and I also know that once it's finished, it's over with. I would absolutely never ever do it again. I fear the thought of dying having only been touched intimately by one woman.

I've rambled a bit, but I hope you can see what I'm getting at. I've never done anything bad to another person before, never gotten in trouble as a teen, never betrayed anyone, and barely ever lied (except perhaps the virginity thing). Please help me solve this or talk me out of it... into it... whatever. I'm listening.

Thank you.

Can you summarize the given text in a few sentences?
<bot>: In a long distance relationship, only been with one woman and can be intimate with another woman (clean), one time only. It would never happen again, what to do...
