Spontaneous irrational thoughts, sex and decisions!?

Im told im addicted to sex. I want it all the time everywhere.
Im female aged 20 and always had a good fun sex life. Recently my sex drive has gone through the roof. Mainly after an argument.. i just want my boyfriend to rag me around and F me! I sometimes wake up in the night horny!
Love sneaking off and having sex somewhere naughty!

Is this normal?
