It seems to be standard advice to initiate frequently and relent only with a hard no. I'm getting a lot of nos, but I don't know very well when it is ASD / LMR and I'm supposed to keep going (and probably get starfish) or if it is a hard no and I should just go sleep.

I also don't really know explicitly what is meant by caveman sex (BPP uses the expression a lot as something to do when getting starfish etc.).
