when you're going to have sex but it just doesn't work out. this isn't when neither person has an orgasm... that's just bad sex. half-sex is so much worse. maybe the guy's dick was inside the girl, but really only technically. it doesn't feel good for either party - maybe it just didn't go all the way in, maybe one of you just didn't know what to do, maybe there was an interruption before things could get good, maybe he had whiskey dick - but ultimately it just sucks. No one was enjoying it, and it never even gets close to being pleasurable for either person. Neither partner would classify this as having sex, and they both end up disappointed.
Friend 1 - "Hey, what's your body count again?"
Friend 2 - "Just one - Tom!"
Friend 1 - "but you definitely slept with Mark too, shouldn't it be at least at two?"
Friend 2 - "Mark was just half sex, so I don't bother counting it."
Friend 1 - "What's half sex?"
Friend 2 - "Well, since he had whiskey dick and his roommate walked in before we did anything worthwhile,. it wasn't even real sex, it was just half-sex."
Friend 1 - "oh! I am so sorry, half sex is the WORST."
