No. I didn't feel different at all. As a matter of fact, it really bothers me when people say stuff like "you don't know life until you've had sex" or "you're not a real man until you've had sex" because you don't feel a damn bit fucking different afterwards. Sex is great, but it is NOT the life changing experience people make it out to be, especially the first time. The first time is terrible.
