Why not have more unisex competitions in the Olympics?

Question

Why is it, that the only time you see a woman and a man paired together in a sport is figure skating. Surely, there is more they can do together besides that

Answer 1

Equestrian! They're not paired together, but men compete against women on an equal level.  

Answer 2

i'd say beach and/or reular volleyball. maybe swimming. and last, diving and gymnastics. also bike riding, but not sure how fair that'd be.

those seem to be the most easily integrated if you ask me.

Answer 3

i think that would be  a  good idea just as long as it is not a contact sport
