I would probably try it at some point but it seems like too much work, jerking off is far more efficient. Also, even if you are packing a big dick, it still seems like it would be at least slightly uncomfortable. The physical discomfort of being hunched over coupled with all that bobbing and sucking...too much of a pain in the ass. But, if I did do it and liked it, I don't think I'd swallow.
Oh and there were times back in the day when I was smashing all kinds of chics but never did the jerking off take a hit. I guess it different for everyone but I was one of those dudes that the more I dumped my load, the more I wanted to dump my load. Marriage of 11+ yrs., four kids and old age takes a little wind out of the sails but I still get mine ;)
I LOVE paying for Xbox Live! I also love that my love for it pisses off so many people.
