Re: Painful intercourse
Wolfgango, I am the "partner" you speak of, in that my husband did just that, largely in part because of my Vestibulitis and our infrequent sex-life: he had an affair. We are divorced now, as the affair was a true pivotal point.
No, I'm not going to try to talk you out of it. Instead, I am urging you to let your female partner go first. -Nothing- is worse than the self-inflicted pain from the aftermath of an affair...this is not just about the obvious emotional pain to your partner, but also to yourself in unforgiving guilt, later on.
Even making the "justifible" excuses won't linger long...that will die out to the cold, brutal reality from your choice of action. Believe me it will.
I'd (somehow) kept a friendship with my ex and in doing so saw his inner-turmoil play out first-hand over the last few years, which is where I'm coming from with all this.
So, the action I urge you to take is simply this: leave your partner first, break up with her first, because if an affair feels unstoppable, at the very least save your partner and yourself the worst kind of inevitable pain that would come very shortly thereafter....
I offer you sincere hugs and wish you the best, as I know you are not a bad person for wanting such sexual desires fulfilled. Of course I do not blame your partner either of what she cannot help, nor do I blame myself for the way I am. I simply hope the path you choose to travel is one that is very carefully, fully thought-out, so the pain that may happen is as little as possible to all involved.
Take care....
