It was many, many years ago. I was, hm, 20 or so. I had a friend, my age, we'll call her C.
We were good friends, and I'd expressed a mild interest in taking things beyond friendship, which was quickly shot down :). However, we were good friends, and we'd do things together.
One day, we ended up at a party.
We hung out, talked, and were both drinking. We kept talking. And kept drinking. And then she threw herself at me.
We made out for a while, and I got to the point where her shirt was off. And, believe me, she was not resisting one iota. However, before it went any further, I had a little flash that cut through my lust and booze soaked brain: "She's drunker than you are. She's too drunk for this. You'd never be doing this if she was sober."
And I stopped, put her back together, and had a sober friend drive her home.
Please realize that I was absolutely shitfaced. A couple more drinks, and I would not have stopped...I would've been too drunk to have realized that I should stop. (I also may have been too drunk to do anything, anyway...booze tends to kill Mr. Happy :)...but the will would've been there.) Please realize that she initiated it...and she never would've done so if she'd been sober. When we talked about it afterwards, she didn't remember a thing. She was upset that she'd been drunk enough to let me get my hand in her bra, but was grateful I stopped it before it went any further. She also said, "I know, instinctively, I trust you." And my reply to that was, "I was way too fucking drunk to be trusted." Luckily, that wasn't quite true, but it almost was.
We thought we were safe! We trusted one another. We had sober rides home if we needed it, or a place to stay if we wanted to do that. But she got drunk and horny and threw herself at someone equally drunk and horny, who liked her anyway. She barely remembered the very beginnings of her throwing herself at me. She was appalled.
Would it have been rape if we'd gone through with it? By the law? Dunno. By her lights? Dunno, but probably. By my conscience in the clear sober light of the next morning? HELL, yes.
One more drink. One more fucking drink. That's how close I was. It haunted me for a very long time.
This is why I tell my about to enter high school daughter, "Take a SOBER buddy to parties." If C wanted to drink, I should have abstained. We didn't even think of that at the time.
