<human>: Condense the text into a few key points

My boyfriend [23M] told me at the start of our relationship that he believed in abstinence until marriage. He knew I [21F] was previously in two committed relationships and was no longer a virgin. Honestly, I realize now that I thought --err, hoped maybe -- he wouldn't hold out and was only saying it because he had never experienced a serious relationship before. We've been dating a year now and not getting sex is much harder than I anticipated. He says we'll probably get married in 5 years and he really hopes he loses his virginity to me then, but I don't know how much longer I can take it. Am I being a selfish nymphomaniac? Are there other couples with one abstinent-practicing partner and one sexually-experienced partner? I have no idea what to do, can someone offer some advice?
<bot>: My boyfriend is abstinent and wants to remain that way until we get married - a projected 5 years from now according to him. I don't have this same ideal and miss sex... Advice? Thank you!
