Too Drunk To Fuck, The Dead Kennedys.
We were in my dorm room. I was playing Dan Fogelberg’s album, Innocent Age. Very mellow stuff. The song during the actual deed was Longer.
I remember vividly because the last line in the song is, “I am in love with you.” We had just finished. The song was just finishing, and she whispers that line in my ear as it’s being played, “I am in love with you.”
Scared the hell out of me. Uh-oh, what now?
You see, she was visiting from 3,000 miles away: she from upstate NY, and me in southern Cal. She was my “childhood girlfriend” (meaning we held hands, big whoop) but I hadn’t seen her in 6-7 years. She visits, deflowers me, and then says she’s in love with me?? WTF??
No music. Honestly, I don’t think I’ve ever done it to music. Never thought about it until now.
In the Chess Booth?!?
Oh, Jethro Tull, 8-track tapes, looping – soundtrack of my youth.
Har! 
I don’t remember what was playing during the act itself but right afterwards, while huge deception was setting in, this song came on the radio, and I will never forget it (especially what happen afterwards).
A Momentary Lapse of Reason by Pink Floyd.
Pink Floyd’s Ummagumma album. I kind of wanted to say “Here Come the Bastards” by Primus, but that was another time later that year. 
Yackety Sax. Should have been a clue.
Rough Boy by ZZ Top. My then-boyfriend was obsessed with them and had a mix tape he played all the time.
No music, but we had just seen “American Pie” in the theater. Her supposedly high morals were pretty easily swayed by an incredibly stupid movie and I lost a lot of respect for her because of that. I was happy that the error was in my favor, sure, but I almost immediately realized that things were better under the “…but blowjobs don’t count” rule.
It was an album by Chad & Jeremy (and yes, it was that long ago). In my mind, though, it was the main theme of Tchaikovsky’s Romeo and Juliet.
March 1968, and I actually remember it was a Wednesday afternoon. Both of her parents were considerate enough to have full-time jobs, so we were in the comfort of her bedroom. The music would have been pop-rock. The only two albums I can remember us listening to during those afternoons were Paul Revere And The Raiders (Midnight Ride) and Gary Lewis & The Playboys 2nd album. I’ll go for comic effect and say “the” song was “Count Me In.”
As near as I can recollect, it was the Broadway cast recording of Sweeney Todd, the Demon Barber of Fleet Street, some Flanders and Swann, Tom Lehrer, and (most regrettably,) ]Loggins and Messina.
But, yeah, at the actual moment, it was totally Angela Lansbury. Explains a lot, I suppose.
Music of the Spheres.
At least I wish it had been playing, 'cause I would like the association from so long ago. But in fact, we made our own music. Now it is called a Golden Oldie.
Sorry, couldn’t help myself.
Round and Round by Ratt.
We were listening to a Top 40 station, and while is was a few years from the charts, it was still popular.
Any club that would have you as a member, eh?
The radio was on and it was somewhere during either This Flight Tonight or Stairway To Heaven. They were on back to back. We weren’t. Heh!
Losing my virginity? None.
Getting to all the other bases? Staind. The album Break the Cycle. Not my choice, I swear. And also it was 2001. So there.

It was November 13, 1987. I know this because David Letterman was on and Sonny and Cher were having a reunion and performing on the show. So the song was “I Got You Babe.”
Closest I’ve gotten so far: Fooling around in the shower with my then-girlfriend back in '00.
What was playing: A Celtic CD called Celtic Awakening.
