KY is nice, but I don't like the warming sensation, it burns me. I like the liquid better than the jelly, too, i'd rather not notice that the lube is there.
Astroglide also kicks ass...my straight friend introduced it to me, actually. We found a sample packet of it on the ground...he put it between his thumb and index finger and rubbed them together, and was like "wow, I can see why the gays like it so much." Like the rest of the day, he was just rubbing those fingers together, i think he liked it.
