It took me a long time to arrive at this descriptor as something i crave in a relationship with a guy. i know it isn't a perfect fit, particularly in the traditional sense, but it fits in a lot of ways.
Generically defined, impregnation is to: "soak or saturate (something) with a substance:
synonyms:
infuse, soak, steep, saturate, drench, permeate, suffuse, imbue, pervade, fill, load, charge"
Yeah, this word definitely works for me. For me D/s relationship and/or Top/bottom, contain the dynamic of opposites where the Dom or Top craves control and wanting to leave Their 'mark.'
For me the "mark" is an expression of the Persons desire, pleasure that gets left inside or as part of me, something He (in my case) wants to leave... almost like tagging? i love to be inseminated by a Guy, but over time i have come to understand that His it's also what that semen represents that fuels my desire. It's a part of Him that is left in me. When He has intense pleasure, i also feel like that is transferred to me by His action and ultimate orgasm.
Kink, for me, offers all sorts of opportunity for "impregnation." The sky is pretty much the limit, but as i see it, the Top/Dom wants a sponge, of sorts, who wants to absorb and be saturated by Him.
