Frustration?!

I'm 27 years old and a very religious woman. I've chosen to save sex for marriage. However, my boyfriend of 8 months has not lived the same lifestyle as myself (he was very sexually active in the past). He's very respectful of my choices, however, he keeps bringing up how sexually frustrated he is. And I can tell he is in a hurry to get married because of it. We are both very much crazy in love and feel that we are destined to be married one day. However, this sexual frustration is causing problems in our relationship. Help??
