Alrighty... Hummm.... Wasn't gonna reply.
I've been involved in various sexual education programs (insert joke here). Astroglide and Wet are both OK, and certainly better than stuff that wasn't made for that sort of activity (KY, etc.), and the price is right. But, um...The best stuff, hands down, ever, ever, ever...Is a product called "elbow grease," and I can't recommend it enough... Like night and day... Several different kinds (get the gel kind not the cream, which is oil-based & isn't latex-safe).
Link for the lazy: Condoms.net (very reliable/discrete)
I'm gonna go somewhere and blush now.
--edit-- just read some of the other posts in this thread a little more carefully. I highly recommend the folks @ the link above. They have the one kind I mentioned as well as just about everything else you've ever heard of (that's just the very best, imo). Same day shipping, very good prices, and free shipping on orders over $50, and option to donate to some considerable amount of your purchase to one of several pro-birth-control organizations of your choice.
