Horny Bf?

so my boyfriend and I have been together for about 3 months now and we've gotten pretty close. long story short, he's explained to me before that he masturbates maybe 2-3 times a week. I don't have a problem with this at all!! however, I only masturbate maybe 2-3 times a month. so its a bit difficult and frustrating when he'll get super flirty all the time and I won't be in the mood at all. idk if this is just a normal thing that I need to just adjust to or what... helpful feedback would be much appreciated :)
