Sometimes when I haven't really cum in a while (doesn't have to be that long), when I get an erection I can flex my kegel muscles and put some pressure on my penis so as not to let it jump so much (like hold it close to my stomach), and it feels really good. sometimes it feels like a mini orgasm. I can do it once and then have to wait a second to be able to do it again because if I do right in a row I can't get that really good orgasmic feeling every time. but I was just thinking about this the other day and wondering if this works for anybody else.
