I was wondering exactly what "blue-balls" meant for guys. My boyfriend mentioned it recently when he was complaining that I didn't go all the way when we were messing around. (I was touching him inside of his pants, but didn't give him a full-out hand job or oral, so he didn't "get off.") Although I understand the basic concept of painful internal pressure building up because of no outlet, what I was wondering was just how much of a problem this is: is it very likely to happen to him or not? There wouldn't be any more than an hour between arousal and an opportunity for him to jack off, and, to me, it doesn't seem like it would be much of an issue since he does so regularly, which, as for my understanding of the matter, would keep the pressure relatively low. I know it didn't happen to him that day, because I asked him a couple of days later, but now it's sort-of in the back of my mind when we're hanging out. Now I'm nervous about getting him turned on, because I feel pressured to do more than that. Its not like I have problems with giving him a hand/blow job, but I don't always want to, for various reasons, and now I feel awkward about doing anything at all if I'm not in the mood for doing something that would get him off. Thank you for your help!
