So I've already had sex but I decided that now I want to wait until marriage but it's so hard because my bf makes me so horny and I wanna fuck him so bad but I want to wait until marriage and I don't want to masturbate either. So what can I do to make it go away?

UPDATE: to answer the question "why wait now"

Well I'm deciding to wait now bc I realized I wasn't ready emotionally for sex and it's the reason why my last relationship ended. And I don't want sex to take over any of my future relationships. Also reading the book "The Bare Naked Truth" by Bekah Martin has helped me.
