All poses should work for both genders as long as your males are not too large in size. However, I created pose 7 for a specific female pose to replace pose 1 (male) for a more feminine stance.
Pose 4 may not work for males with larger arms.

Codes

a_bmit_flowerdate1 (holding bouquet, thumb hooked into pants)
a_bmit_flowerdate2 (holding bouquet with two hands)
a_bmit_flowerdate3 (handing bouquet over)
a_bmit_flowerdate4 (taking bouquet from pose 3, hand on chest)
a_bmit_flowerdate5 (holding bouquet for pose 6)
a_bmit_flowerdate6 (smelling flowers being held by pose 5)
a_bmit_flowerdate7 (female version of standing at front door)

CC Used With This Set ( you may try your own and see if it works)
