I have been thinking about this for a few days - appears no one else has
Anyway, I got a bit confused with the word partner.
If you have a long term partner or someone you wish to be long term, then yes, I have discussed and would discuss any size issues that come up - positions, thrusting, how long you are comfortable inside etc etc and you make mutual compromises, and still enjoy the sex greatly because it's about the two of you.
However if you are just having sex with someone, I would discuss any issues and compromise, but like women who prefer size and don't go back, I like compatability and wouldn't go back.
I may be shallow, but I have had encounters that have not developed because of incompatability.
I have a bug bear that is the tell tale sign for me and I have mentioned it before. If she always have to go on top, then I end up feeling like an object and get bored - I imagine many women will empathise with that - lying back and wondering if the ceiling needs redecorating. It sounds harsh but it just doesn't bode well for a good sex life to me.
