I've been a big fan of the clit orgasm since in my teens and I have a gf who I've been with for a number of years, we're totally a great GGG match. I know my kegels and building up to squirt, though have had problems in the past orgasming with partners.

I've been learning to love penetration more -- like really love it -- I've had some lovers in the past who didn't really do it for me in that department so I figured maybe I just wasn't into it, but I'm finding I totally love it.  But we'll be going at it, it'll be building, it'll feel incredible, I'll totally lose myself and my inhibitions, but it suddenly seems like it'll get to a certain point and I'll feel myself welling up to cry...and I'll pretty much need her to stop because I'll burst out in tears. What the heck is going on?    It doesn't feel like I orgasm, it feels like I fall just short of the awesomeness.  It sucks because it totally kills the mood to keep going, my 'parts' go stone cold and have no desire to continue as I need to bear hug clutch my gf for dear life and wail.

I did some looking online (hetero opinions) and some bs came up that it was either because 'it was beautiful sex'  or the 'woman was upset because she couldn't say 'no' to not wanting sex.'  It's totally neither for me.

Does anyone else know what I'm talking about? I can't imagine it's just stress - do I have some emotions pent up or something and should watch a tear-jerking cheeseball movie to get it all out beforehand? Or was that actually my orgasm - a big ball of tears? I don't want to exclude her awesome manual penetration into our routine, and I don't so much need it to end in orgasm because it feels so incredibly good regardless, but I just don't want it to end with me crying all the time.
