I have a much younger friend of mine who is in some relationship problems that started with just having sex with the girl. Now he is kind of caught in a relationship that is difficult. He told me that in his teens he thought having sex was everything and he would have hitch hiked across country and slept in a ditch to get laid. Now he would not be so over anxious.
He is 25 and I am 40 (almost). I told him that when I first got married 12 years ago I was with my wife usually several times a day, and now if I am watching re-runs of Bugs Bunny cartoons and she stands naked in front of the TV I would ask her to move. Sex, although always fun, at some point no longer is the only reason for living.
Right now just having sex has to be an exceptionally powerful drive for you, especially if it would be a first. But at some point it will take its proper perspective - and you will continue to find time for sex - in between commercials....LOL
I say, resist this temptation. I had a remarkably similar experience a few months back. Married hispanic girl came in the office, we were caught alone, she grabbed my hand and started carressing it, she said she wanted to kiss me. My wife and I have been married 12 years and I have never even kissed another woman, but I almost did this one. She was hot, it seemed VERY exiting - kind of the exitement I remember when I was young. But in my mind I knew however exiting it seems now, it will be essentially the same as every other sex. What makes it exiting is in your head. I knew that at some point I would be facing a lawsuit, an angry husband, my own divorce, huge expenses, and who knows what else. So I wisely refrained. For a few days I sort of kicked my self for not 'going for it", but now I am sooooo glad I did not.
Your first time will be exiting no matter what. Wait for something safer. Or as mentioned above , let her swallow the evidence. Do not have intercourse. If she is angry at her husband, getting pregant (with YOUR baby, traceable by DNA) would be the perfect thing to throw in her husbands face. Don't let her do it. If you can't resist, feed this hispanic chick the burrito and let it go. But I gaurantee you, she won't let you walk away easy once you have any form of sex. Girls are needy people and estrogen makes EVERYONE crazy. I do not believe in roid rage, I truly think it is the estrogen that aromatizes from the testo that causes problems. Estrogen is insanity in a bottle.
My number one choice for you is walk away, take it as a compliment that someone finds you attractive, let it build your ego ................
