Sandy well i think a belt would be way worse then I thinks. But I don’t want to let my urges make me loose what’s important in life. So if not a belt I need somthing to save me from myself.
You have to learn self-control. A chastity belt is not helping to learn it. It only affects the impact by not being able to satisfy yourself, but it will not reduce your urge. On the contrary, if you read how it is for others who have to wear one. It will get worse and will distract you even more from what is important for you.
If your urge is greater than the desire to go to MIT, then apparently MIT is not really important. Then drop it and go to the school nearby.
How about you seek professional help if you want to solve your problem and you can't do it yourself. There are certainly help groups, organisations or even offices that can give you support if you really want it.
