I have BIG nipples! But it wasn't always like that. Like most men, I came into the world with goose-pimple sized nipples, but decided about 4 years ago that what nature didn't give me; I would give myself. Tit men, the curious and the serious, often ask me what techniques I use to enlarge my nipples, and I tell them:
For me, nothing can replace a long hot mutual tit workout with another serious titman, suck, pull, tug, and S-t-r-e-t-c-h those tits until you can't stand it anymore. And then we start over again, and again, and again. If you're not sore for at least two days afterwards, then you haven't worked on them long enough. Human flesh is very elastic, and if you pull on those tits long and hard, they'll respond and stick out -- long and hard.
Clamps are useful because they leave your hands free. Find a pair or two firm, but comfortable tit clamps, if you want to stretch out your nipples without too much pain. You should be able to wear a one pound weight on each tit for at least 20 minutes. You can also put a piece of elastic behind your head and attach two ends to your clamps, and stretch your tits UP! Of course, using clamps with your buddy can be hot. I like to lay my buddy on his back, throw his legs up in the air, and, using a rubber, fuck his asshole real hard while our tits are joined together by two pairs of clamps. Talk about hot!!!!
Suction cups really work! It may be difficult to have a hungry mouth sucking on your tits four or five hours a day, but you can wear suction cups practically all day long, if you want to. So far, I've found that the snake bite kits commonly available work best. The kits come with two wide suction cups and one long and narrow one. So if you want long, narrow nipples, buy two kits. Grease up your tits before you apply the suction cups (not vaseline since that decays the rubber), squeeze some of the air out of the cups and stick them on your tits. A few minutes later, squeeze out some more air. Continue in this way until there is no longer any air in the cups --just tit. Caution: at first, don't use the cups for more than 15 minutes or so, or you might get blisters, little by little, you'll build up resistance and be able to wear them for hours on end, thats when the real enlargement takes place. If you wear a shirt with two pockets (to hide the bulges), a vest, or a jacket, you can even keep on the cups at work. But again, watch for blisters.
If you decide to have your nipples pierced (as I did); do it AFTER you have enlarged your nipples with clamps and suction cups, since the rings and bar you put on will get in the way of the clamps and cups. Once the holes have healed, use weights and elastic bands as you would with clamps, the piercing itself will cause the nipples to swell, and some of the swelling will never go away. In fact, I once met a man with nipples almost as large as mine who got his tits big JUST through repeated piercings. He would have as many as six needles inserted through each tit at one time. If you decide to have your nips pierced, put in a bar or ring that is as thick as possible: those thin ones are no thicker than wire, and they tend to cut your flesh when you hang weights from them. Connect your two rings with a heavy chain. Walking and dancing become new erotic experiences, as the vibrations of your movements are transmitted to the INSIDE of your tits. It just might give you a permanent hard-on.
