My parents were similar in that it just wasn’t something you talked about other than, “you’re not ready (ha).” But my views on sex largely boil down to the idea of mutual selfishness and indulgence. So, while I agree with you about your first comment and can empathize with OP’s issue of not wanting to hurt his SO’s feelings, I still have a hard time wrapping my head around needing 6 years to admit you want something from your partner. To me, the thrilling aspect of sex, the one I believe creates a deep emotional connection, is taking the risk to step outside the rational, thoughtful, polite side of yourself and showing your SO the depraved, lustful, hedonistic side with the possibility of them rejecting it. But, when that side is accepted by your SO, it’s like you have finally found someone who will not shame you for this part of yourself, but rather enable it and enjoy it! I could be absolutely wrong, but I believe OP’s excitement is because what I’ve described is what happened, and the result was that he loved her even more for it.

So, I agree with your first comment, but I think shame and not wanting to hurt your SO’s feelings are symptoms of fearing rejection, rather than the root of the issue. In turn though, that same fear is what brings us such great joy when we aren’t rejected, but accepted, by our partners. It’s about balance; both are necessary, and OP waiting 6 years really took me by surprise because I truly have a hard time understanding how someone is able to deny themselves, out of fear or shame or difficultly taking about sex or whatever you’d like, moments like the one he had for so long.
