If it gives you some idea, nogbad's The Gift of Words (an incomplete dark hurt/comfort WIP which is up to 12 rather long chapters) is many, many thousands of words of much comfort in comparison to maybe 1 or 2 chapters in toto of anything specifically sexual happening.

Realistic amounts of healing and comfort are good. I think so long as it's pointful people won't mind.

If you snap in the middle of it and feel the need to do another naughty omake, that's your bidness. XD
