Is it normal that I feel the desire to do this now that I've had sex?

I wouldn't tell any of my closest friends this, because I doubt they can relate but now that Ive had sex and had an orgasm and all that I kinda want to masturbate? I'm only 16 and my bf was a PRO, I swear. He was 24 and knew all the right spots to hit. He turned out to be a douche tho and used me.. :/ but I miss having sex! So since doing it with him isn't an option, can I create a similar feeling myself??
