Am I a really slut, or things like this are common?

OK, this is what happened, I was on my way to my hometown in a bus at night. Ok so I sat close to this handsome guy. We started chatting and yea admit I enjoy his conversation. Ok at Midnight I fell asleep and hung on his shoulder. He started touching me and true it was a very good feeling. We just started kissing as the lights where off. I let him put his hand inside my jeans and all that, I did the same for him, by the way we had these small blankets so it wasn't that explicit to other pengers. oK we was both ready, eventually the bus stopped at some garage for a snack. we snicked into the ladies together and did it. Partly I regret for being this cheap but I admit it was the most pleasurable quick thing I've ever done. We exchanged phone numbers. Amazingly he hasn't contacted me yet, and I am very ashamed to do so. Has anyone ever done this kind of a thing or am I the only one. Thanks for all your answers, I will accept what ever you wanna call me, but please don't be too judgmental, thank you. iI've never done this before it was my very first time.
