For the altruists in the crowd...
I'm not sure how I missed this thread, but my S/O and I have a special position. It rocks her world every time.
We start of with good 'ol Cowgirl to get her warmed up. After she has cum, she lies on top of me, face to face, with me still inside her. She then slowly grinds against me. There is usually a little work in finding just the right position until she hits what we presume is her G-spot... although she says it is much more intense than that (the "Gee-whiz" spot?)... and when she does, look out!
When she comes this way, she just collapses and usually falls asleep for a couple of minutes as it is so intense.
The down side is that my dick gets squished to death and generally it is necessary for her to blow it back up... not that this is a bad thing.
This position is very intimate... lots of kissing, back stroking etc. and she loves it...
We discovered this by accident... but it's worth the effort to try to make it work...
