The folks who posted before me pretty much covered the bases - it is totally possible to be poly and a virgin. Uncommon, maybe, but certainly possible.
Feel free to ignore this as your question has been answered and I am asking out of my own curiousity - what does virginity mean to you?
It took me much longer than my peers to have sex but that was not a completely conscious choice - rather a combination of introversion and an utter inability to recognize flirting. So I am curious about folks who decide to be virgins consciously and thoughtfully.
