The main goal of the experiment is to determine the physiological effects of long term orgasm denial.  Using twin studies is the most efficient way of eliminating other factors such as base hormone levels or other genetic predispositions.  Essentially, one of you will wear a chastity belt for a six month period, while the control subject goes about his life as normally as possible.  There will be regular blood tests and monthly evaluations by a counselor for both of you.  Naturally, you’ll both be paid the same amount for your participation.

Of course, since you’re twins, it doesn’t really make a difference which of you is the experimental subject and who is the control subject, so we’ll leave that decision to the two of you.
