With few exceptions, behaviors are "feminine
" (or "masculine", for that matter) only relative to the traditions of a given culture
. The exploration of your "feminine side
", then, must proceed from an understanding of what femininity means to you
. Hint: Children usually have a remarkable sense of gender role
by kindergarten; examine your memories
of what the influential women in your early childhood were like, and you'll be well on your way to contacting "your feminine side".
That's certainly not all there is to it! These instructions would be unnecessary if people naturally and effortlessly identified and embraced the aspects of themselves that conflict with their gender roles. Cultural gender norms are enforced (often subtly, sometimes quite brutally) from every direction - peers, influential adults, the media, the arts. For many men, "getting in touch with your feminine side" means sifting through a whole lifetime of enculturation, weighing tradition in light of reason, and getting over the real or imagined stigma attached to "feminine" pursuits.
Smooth, mutually rewarding relationships with feminine people (including women) do not come without understanding and cherishing femininity - in others, and in yourself. However, if "feminine" describes certain strengths, certain weaknesses are traditionally "female" as well. While getting in touch with your feminine side, you may want to also recognize your effeminacy, such as it may be.
If there was no resistance, it wouldn't be a personal victory - so get out there and show the world what a man you are, by doing something "feminine"!
