Ok, so I posted over on the e-highway board about increasing vaginal tightness through kegel exercises, but am hoping for some more "real world" input from you ladies.

Here's the situation.  My ladyfriend and I have incredible sex, but for one area....intercourse.  She's not very tight, and this is compounded by the fact she gets VERY wet.  Yes, an incredible turn on obviously, but it very much decreases sensation for me, to the point that with the two issues combined, I can virtually feel almost "nothing" unless it's our first go around after an extended period of abstinence.  And then trying to go more than once in a weekend?  Forget it.

Again, we do not suffer in bed.  At all.  The other activities are incredible.  But we would like to make love more.  

Any suggestions?  Positions?  Is there a good, safe way to (and I hate to say this because I realize this is a healthy reaction and an incredibly "good" thing) decrease the "slickness" or lubrication?

What are your experiences with kegel exercises?  Do they really "tone things up" and make a difference?  She seems willing to do what it takes, but we'd like to not be chasing after pipe dreams either.  

I imagine some of you ladies must be in the same "position" and may be more educated than her and I how to make this one aspect better for us both.  Or do I "call it a day" and just consider ourselves incredibly lucky to have it so good in every other area?
