uh, this story sounds familiar. I feel like I know the guy in this couple which brings me to this point..is this someone you would consider marrying? have y'all discussed marriage?
i have a friend that had had sex with this guy she was dating (not daily but maybe weekly, they lived separately and had jobs, etc). well they got engaged, decided to live together to save money (as roommates), decided not to have sex for religious reasons. they lived together while engaged for a year and only had sex once. she initiated. there was guilt (or maybe lack of interest) on his part. they got married. recently they hit over a year of NOT having sex and they are married. it was sporadic at best even after they got married. now it's non-existant (for over a year). lots of hurtful things have been said in both directions but this is by far the biggest source of their marital discord. divorce is being discussed!!
i shared that to tell you to really consider whether the going without sex is possibly a sign of a deeper issue. i don't know how old you are. if you're a teen maybe it's a non-issue but if you're in your 20's or 30's you need to really think about this. if nothing else you two might just not be compatible in an important area (sexual compatibility). i'm a christian too and i really want to not have sex but i'm a very sexual person and knowing my friends story makes me very leery of a man that can be with me and decides not to have sex with me. if you don't want to have sex because of it being a sin, put a right on it and let's do it!!!
just my two cents...
this is something you have to be very careful with. In order to do this, you almost have to "train" yourself to not be physically attractive to your mate. The longer you do this, the longer it can take to "unlearn" this.
I've known couples like this as well, who were shocked to discover once married that they didn't get along in the bedroom, after years of not having sex before marriage. It's one of the reasons why I feel pre-marital sex is important...so you can assess sexual compatibility. I don't think human lovers were meant to spend years together not having sex. Religious "courting" couples tend to get married sooner rather than later for that very reason. A man who could just turn it off and abstain would raise red flags for me.
