Especially considering that I know next to nothing about intercourse beyond the textbook to be able to play that without making it read like an IKEA manual.
Describing the rush of emotions, thoughts, sensations, nervousness, excitement, determination, and other reactions to sex turns out to be
exceedingly difficult to do in text. Especially in EVE, where you're limited to barely three sentences per post. There's a lot going on during those [average] 30 minutes.
There's a lot of bodily functions going on. Hormones flood your brain, all five senses flare up like a Lite-Brite on steroids. Everything about him/her is hitting you full force, and your heart is pounding. The scent of their body, the way they look, the sounds they're making, the way they are touching you, the taste of the kiss.
The anxiety of what's about to happen, a nervous sense of anticipation, the determination to do everything just right (or just to get off), the knowledge that you're about to get it on like Donkey Kong. Your brain is running a mile a minute, all while you're still trying to get your fucking necktie/brassiere off.
Then comes the bumping and grinding, and a lot of it. Some pretty disgusting sounds happen there, and it's usually not all that pretty to look at down there either. Kinda weird actually. Why did I look at it? Oh god, am I losing wood/wet?! Quick, think about their [sexy stuff]!
Sex in real life is confusing as shit, stressful, chaotic, and not at all scripted or legible in any fashion. It just sort-of happens, and you take a tumble in the sheets for a while only to flop over panting and sweating. Unfortunately, chaotic confusing and stressful RP is not easy to do in EVE unless it's the IGS or Summit, and unless you rock out with your cock out while you trollin' dem scrublodytes in those venues... you probably don't get off on it either.
So most people ERP like an IKEA textbook. They focus on one coherent thoughtline for the roleplay, like... the way the genitals are rubbing, or something. It's simple, and "boring", and not at all like the real thing - because it isn't the real thing.
Sex is not ERP. ERP is not sex.
Don't go into one expecting the other.
