Also aware of my girlfriend falling under its spell as she did a hit after me. The effects kept growing, looking at a full moon, fell back, amazed at the pure intensity. Holding my breath like smoking a bowl of grass, as we had already done.
Then holding it long as possible, feeling a throbbing state beginning to grow from my chest. I did my first hit, following Sheri Lee's example of breathing in deep, one nostril pressed shut. She took out the bottle, and said she was going to do a hit or two, and we could share like we had the couple of bowls earlier in the evening. The other man was a friend I had been jacking off with for several years, though we never touched. With my first girlfriend on a warm summer evening, five of us sitting outside in a brilliant cloudless night, our first year of college past. Sheri Lee is the actual provider of the first poppers I ever inhaled. Among other things, as it turns out, because the effects are enhanced through drinking and smoking. It is not really an aphrodisiac per se, since it is by far most seductive to use when already thoroughly turned on. This is the place I remember specifically reading about this 70s sex drug, though it was not presented in that fashion exactly.
My very first knowledge of what has become a long time addition to enjoying sex is likely to have been before first reading about 'locker room' and its old socks smell in Playboy Potpourri in the August 1976 issue.
