I read through my post and I noticed that I only really gave the negative points about the experience.
so..
When it first hits you its gonna be a ton of bricks, a major rush, unlike any of the smaller drugs like weed, shrooms whatever. Then your slowly gonna come down from the rush and be nice and calm. Not so calm that you wanna sleep, coz you won't be able to anyway
but just a good calm. Colors are gonna be brighter, your gonna see things that you've never seen before, or perhaps you did but now you see them alot differently.
If you have girls around that are also gonna be tripping its a good idea to hook up with one, not sexually, (well unless you want to i guess) It's sooooo nice to have someone that you can touch, rub her arms, her back, neck. Whatever, she will touch you back and it'll feel amazing, it'll be warm and.. well.. hard to explain really, but its in fact amazing.
On to Sex while on E. Some people say once you've had sex on E, you'll lose all drive to have sex unless you on it. Some of my friends tell me it like having an orgasm..... times ten..... on your entire body... inside and out. I don't know I've never had sex while on it, and I dont do it anymore so maybe someone else will be able to let you know about that.
Everyone on this thread is giving valueable information, its in your best interest to read up about precautions. Having sober people you trust near you at all times.
