World Enough and Time

I really did not do a good job at presenting my points

I thought you did - and you raised a few points I still want to comment on, if only I can find the time.

Sex with Jack is something that strikes me as about being about life and connection and fun and play.

Yes.

I'm not saying sex is a huge sacrifice for him (er, duh?) but it certainly is something he can give of himself to people he likes and cares about.

Yes. He's very sensual and enjoys the physical, but it goes beyond the physical for him.
