I have drippy hands, was married 15 yrs and had several long term relationships. What's interesting is over time you'll find that when you are alone with that special someone, HH can be under control. That is when you are alone with them.
That's a nice thing to look forward to. Still, can't picture myself not having the faucets in situations were some excitement (good or bad) is going on. For me pretty much any strong emotion negative or positive, temperature diffs or physical activity turns on the sweating (and turns off the woman

).
Anyway to answer the question; I once had some contact with a girl who suffered from HH pretty much the same way I do, she lived whithin a reasonable distance from where I live and I reached out to her on a HH forum in my native language. 'Twas some years ago so back then we exchanged emailaddresses to chat via MSN, exchanged photographs etc, had a couple good conversations. It reached the point where I was really thinking about do I take a next step here or not. Thought about it a lot, decided against it. I just figured in the end both having the same affliction isn't the best basis for a relationship, especially not long term where you might even think about some very sweaty offspring (I wouldn't want that on my conscience). I kinda let it bleed to death before it got close to potentially dating which was a lame thing to do either way. Sometimes regret that decision but simple fact is, IF you look for a relationship and you're not intend on ending it whithin a certain time from the get-go, in the end I think it's going to be a bad situation when you both have the same affliction.
I think I'll have to find me an HH-less woman who likes to be with me despite the HH and who I like to be with regardless of my own HH situation. That however is one of the trickiest things with this thing.
