So, I’m on my period and I’m both moody and horny and I don’t know what to do about it

I’m 17 so technically it would be okay if I watched porn, thing is, I’m an innocent little thing who hasn’t even touched herself (the boyfriend does that stuff, yet I’ve been distant towards him and we’ve never sexed or anything close to that). I usually sleep it off but it’s too early for that and I’ve got things that I have to do yet. So are there any other ways that I can get rid of the feeling or at least satisfy it? I probably could try watching something but I don’t feel like experimenting with the boyfriend even though we’ve been together for a year plus.
