For me, I (broadly) like some form of sexual contact in every 24 hours I am with the other person. Might be my orgasm, might be his, might just be playing..... This is true with the current one, my most recent ex (LTR)), and DD’s dad (the one before the last). Less good for me with those before him, as I recall....
Sometimes one might be poorly, sad, having a row etc, so it doesn’t happen - but In general for me, some kind of sex is the norm.
If it stops altogether in a relationship, I feel sad and bewildered. To me, it’s an important expression of togetherness. And so healing! With the current one for example, few times we’ve rowed, we have NEEDED to be in bed together afterwards to get over it. It’s the most beautiful way of showing one’s romantic love, in my opinion.
For those of you living without it, and missing it, I would urge you not to ignore those feelings....
