Masturbation Question?

Hey Guys, quick question for you all. Obviously I am 18 and I masturbate (shocker), but here is the thing. Since I got older, once a day isn't cutting it now and I want to go 2-3 times a day sometimes, I just cannot resist. There are times I need to just go at it to calm me down and everything is good again! haha Anyways, I have this feeling that I must take a shower after jacking off. I know not showering obviously won't impregnate people from my penis touching the toilet and stuff, but is it unsanitary? Other guys, do you jack and go and skip the shower after or is it essential too? Like obviously I wipe up and stuff when I finish, but is that gross to not shower after masturbating?
