Anyone else?

I’m currently single, haven’t had sex since probably September. I masturbate regularly to relieve tension, stress, etc. and I’m really not one to hook up but lately I find myself really desiring sex. I’m a Christian and I really want to wait until I’m married even though I’ve had sex before but it’s getting harder. I think about the sex my ex and I used to have and physically it was on another level.. I don’t know what to do
