Kinda this. What the hell do you DO during a blow job? I'm not very vocal, so I feel like I'm just sitting there, going "You work, I play." This isn't to say that I find blow jobs boring, because they are, in fact, great. It's more of a guilt thing of me not contributing to the experience as a whole and I feel like jerk, which is probably pretty offensive to the effort being put forth by the nice young lady with my genitals in her mouth. If there were some way to fill up that vacuum (ha ha) of time, like playing video games or doing calculus, I'd actually be DOING something. Someone nailed it on the head several months ago with the whole "guys aren't in control so they don't like it as much" commment, although I feel that in my case it's not so much a lack of control as a lack of activity.
