am I a perv?

So I get very horny before my period and it's been a few months since I had sex for the last time. I was on this family vacation and the hotel we were staying at was overbooked so mom, dad, older sister and I had to sleep in the same room. I was very horny and I locked myself up in the bathroom and masturbated till I had this great orgasm. After that I felt like a perv. am I?
