As I matured, dated, traveled and learned, I realized that sometimes sex, relationships and intimacy can be a guileful thing. Sometimes we become involved with someone we later find out is married and suddenly have a whole new set of issues to factor in. Admittedly, I have slept with married women, one knowing and one not knowing. In the latter it was a classic case of traveling on business, to find out after the fact in an email convo. In the case of sleeping with a married woman, it was hard issue to tackle as she was upfront about her marriage, but very aggressive and single minded in what she desired. And since the very first flirtatious conversation, I showed no sign of seeing it as a barrier, it only emboldened both of us. And so we pursued something physical in nature and it last for a while. Yet, the emotional subterfuge and general lack of "truth" proved the downfall of an overall vigorous sexual relationship.
And I've read in several posts, inevitably bad things happen. And generally, they are right. I think one has to weigh short term physical gratification with the potential emotional consequences of their action, like most things in life.
So when I think back on it now, it taught me how to be more emotionally aware, cautious of emotional bruising and generally to be a "better person" even when I might be involved in a relationship that is considered verboten by society at large. All I can say is...Damn You Libido!
