Regardless of whether I was granted permission or not, I couldn't do it. I'm just not wired that way, I can only have sex, kiss, make out, be intimate, etc with someone I love or have feelings for. Since that is and will always *only* be Synthetik, my fiancé, I could not do it.
While, yes, like S,L&L, Sex is *very* important to me, in the end I would manage with what Synthetik was able to do and, of course, with the aid of toys. Besides, even if he gave permission, I know that Synthetik would probably be upset in feeling that he could no longer satisfy me, and therefore felt that he had to have others do it (I've heard that gents take very seriously whether or not they're able to satisfy their ladies). Even if I were wired differently, just knowing that I'd be out, having sex with some other man, while he'd be at home torn up because he couldn't do that for me, I'd feel terrible. And if the situation were reversed, I don't think I could extend that permission to him, and if I did it'd tear me apart, just like it would him.
Now, other people will have differing opinions from mine, and there's absolutely nothing wrong with it of course. But that's just how I feel on it
