If a guy is concerned, great advice here.

Simply put, alternate roles and situations, make sure that all partners orgasm equally, talk openly, actively listen, and build tust and safety.

If there are partners that are asexual or struggle (or can't) that is ok, then it is up to the partner to provide pleasure in an equal time and amount. E.g. foot massage, full body massage and all that.

Curiousity is critical as you call out, but also want spice? Find those intimate taboos that give each partner a moment of pause. Talk and find out how one can utilize that to add thrill and go for the gold.

One doesn't have to do "it all the time", but a little here and a little there like salt and spices takes something bland into amazing.

See a fun flip the roles and switches could be ... you will be served breakfast in bed (with hot coffee). You will be pleasured while you eat and if you spill, you will be spanked in the shower ...

I agree with you on the PIV view. I do realize for some couples that is the primary and sometimes only way that one or both couples can "orgasm". This is ok, one isn't defiicent unless there is an orgasm gap.

The key then is to find the other things to make one can go ... "yum".

Hell, one can make a game of the orgasm inequality gap in saying we are going to emulate the percentages in reverse as a couple say for 90 days.

So that would mean she orgasms 95 times and gets to 65 times ... yes ... she comes every day and he comes 2 out of 3 ...

Let the games begin!
