Is this possible?

Okay so I started my period today and my sex drive went THROUGH THE ROOF! My boyfriend is in the military and was unavailable atm. So I started reading some sex stories/porn (o don’t watch porn, I read it) and looking on my fav kinky/freaky pages on Instagram, just now, I had one of the most distinct, climactic orgasms Ive ever experienced but I never touched myself bc I wasn’t in the mood to get messy. Is that possible or normal? I mean I was doing a lot of imagining and moaning I wasn’t sure if there like...has to physical contact to have a real orgasm??
