blak9: I'm with all of you guys. I've only had one ex gf who could make me cum by giving me head. Although she gave the best head of my life, it still usually took me about almost an hour (no lie) to ejaculate and that was only after she made it extra sloppy and used both her hands. Any other time I have to insert into the vagina to bust one.

I agree with ericbear about the good face-fucking doing the trick but how many of us here can do that without gagging the poor girl on the receiving side. To avoid this I didn't actually stroke her face but just did a little back and forth rocking motion.
