RunnerDNM: I'm going to shoot straight with you here, and I'll tell you in advance you're not going to like what I'm about to say. You can take it an use it to help yourself or you can blow it off and say I'm an ass. Either way is fine.
[Boundaries are lines that we shouldn't cross without permission. For example, my waiting room is a public area. People come and go at will. However, my office is private and it is proper to wait until being invited in, even if the door is open. A property line is a boundary you shouldn't cross without permission. The same way, relationships have boundaries. These are mutually agreed upon expectations for behavior. Some couples, and I don't think it matters if you're gay or straight, believe in total exclusivity. Others say oral sex is OK but not intercourse. Some couple allow contact with other people, but only if both partners agree. Some have truly open relationships, where each is free to do whatever he or she pleases with anyone. Each of these are examples of boundaries in relationships.
From reading between the lines of your post, it is evident that you have some problems with boundaries. Inadequate boundaries can result from abuse, trauma, or simply from never learning proper boundaries. I'm not trying to be a smartbutt, but a person with intact boundaries would know that you being naked in the same room with someone was probably going to lead to sexual activity.
Again, I know this isn't what you want to hear, but I think your focus needs to be working on
you right now, instead of trying to win back your partner. I'm going to give you a starting point in the form of a book. I'm a firm believer in people educating themselves as a way to change their self-sabotaging behaviors. I suspect you'll need to go beyond that with an individual therapist however.
Here is a link to an incredible book on the topic. There's no reason to pay a therapist to give you the information you can get yourself. But once you have a basic understanding, I think you'll need to follow up with a therapist with experience in dealing with this. One caveat, it is written from a Christian heterosexual perspective. However, I don't think the same concepts would apply to any form of relationship.

I am in no way affiliated with Amazon or the authors, except that I use their materials with clients in my counseling practice. I receive no financial consideration if you purchase this product. I'm not intending this to substitute for actual therapy, which I think you will eventually need. You are deep into a pattern of self-sabotaging behavior, and I hope you will take the steps needed to break this cycle.
