Hi!

Welcome to the BP Forum here at PC.
I hope you will find the support and the information you may be seeking.
Hypersexuality is a common theme here, due to the nature of both hypomania and of mania. Still others deal with hypersexuality, as well, for whatever reasons.
So, you'd had enough insight about your planned behavior to write about it here -- before you'd participated on that day. So insight, alone, is not enough to stop these behaviors, in your case. By the way, you are very fortunate to have insight like this.
Often, when people are suffering an "addiction," they go ahead with the behavior(s), even with insight. They might feel a compulsion to somehow fulfill their "need." An alcoholic feels a compulsion to drink more alcohol, for example. In many cases, this makes people feel worse about themselves. For example, an alcoholic might engage in drinking for immediate satisfaction; yet, then may feel increasingly defeated by this drive for alcohol. S/he might also suffer in many areas of his/her health and life due to this addiction.
The same goes for sexual addictions.
I am not diagnosing you as a "sex addict." I am not qualified to do so.
Maybe you can see a therapist who specializes in sex addiction to learn more about yourself and about your healthier options?
I hope you will make yourself at home here at PC!
