how will I know if I've reached my climax or had orgasm?

First off are you a guy or girl? I'm a guy but all orgasms feel the same! It is a massive rush. You will just know when u have an orgasm. It is the best feeling in the world. U will feel tingly and breath heavy and there is no good way to explain it because it feels so good. If your a girl your nipples usually get hard. I love masterbating. I get completely naked and use lots of lube and stroke my hard penis. Ill imagine a hott girl with a nice round ass and big vagina lips with her legs spread and me on top thrusting in and out while she tells me to keep going and I just imagine sucking on her puffy nipples and holding her butt and being deep inside of her. It gets so intense then ill explode and imagine her cumming at the same time with her p***y juice flowing out all over my hard penis. Its fun. Orgasms are the best. I love masterbating.
