Been on both sides of this.

Am also a virgin waiting on a spouse from God, but have had more experiences in this area than some.

Sometimes I think the way you do when I consider people that have had a lot more sexual experience than I. But on the other hand, when I think about men that consider me that have had less sexual experiences than me, I wonder if they feel the way I do about guys with a more "checkered past".

All I can say is that sex in a marriage is not comparable to those outside of marriage. There is something supernatural about it, and the more you and your wife are closer the Jesus, the more this will be true.

Sex in marriage is always going to be the best someone can ever have because it's within God's design.

I think your problem isn't your wife's past but just everyday irritations that come with marriage.

I suggest you really pray about this consistently. Your feelings are valid though, but as your family grows closer to God, these feelings will probably go away.

Also, your wife has a whole kid with you, that's some next level intimacy. Don't discount this!
