Look at the associations -- some or all are resonating "consciously" or subliminally in semantic noise:

           |------------------[gender]
           |-------------------------[pornography]
           |-------------[flirting]
           |--------------------------[competition]                                                         |---------[mystique]
           |---------------------[appeal]
           |------------------------------[reproduction]
["sex"]----|----------[tribal role]
           |--------------------------[hormonal urge]
           |------------------[lust]
           |--------------------------[passion]
           |---------["privates"]
           |------------------------------[scary] 
           |-----------------------?
           |--------------------------------------....

Do you enjoy being noisy? Do you enjoy confusing? Do you enjoy scaring?

Much of the time, you can avoid this by simply saying "gender".

And, instead, of "having sex", celebrate erotic love.
