I think I'd have to say that enemas have been a gateway for me - it may be more accurate that the partner that I have been exploring with opened up my eyes to a whole new world and enemas were part of that. But I think that the intimacy of enemas - the trust, or bond, I have with my partner, and His acceptance of me for me, was just multiplied ten thousand times by enemas.
I may or may not have explored my sexuality without enemas - but I can't imagine NOT having enemas as part of who I have become, or will become. There's no way I can ever go back - I don't want to, and my enemas are a direct link to my kink that gave me my courage, or confidence, to let go and follow my heart. Finding out enemas are so - fantastic, versatile, and able to be much more than putting water up my butt, blows my mind. They enhance everything about being intimate - they establish a trust, a common experience shared between two people. I know this all sounds sappy - or sentimental, or retarded, but enemas, and the right partner, really did it for me.
Enemas were definitely a gateway for me - they lead me to my first ever woman-2-woman experience, the 'slap my ass and pull my hair' whip and ride buckaroo, not to mention regular anal sex for a used to be kinda vanilla grandma. Yeppers - put me down as saying yes to gateway.
