Is talking about a sin?

I ask a myriad of q's on here about . Just to broaden my understanding, of the topic, n also to see if my ex was totally off base in his varying allegations against me reguarding the issue. I've made some friends on here, simply due to my frankness to the subject. I dont view it as vulgar; but rather an expression of the love or pion two ppl share for each other. God created it to be within the bonds of marriage, so what 's so wrong in talking about it to mature audiences? Anyway, I've made many guy friends on here(judging by avatars), n i believe it's due to this subject. And some have even started maliling me regularly. They also do open up about things, n experiences. But it seems they want me married, since through my writing, I seem like a wild woman and my thirst shall be quenched. And, I was on this matrimonial site, met this prospect online, and the first couple of q's were ual. I asked him y he was asking, n he said he was just making conversation. Y would he chose as a conversation starter to a girl he doesnt know? And y would the previous guy want me married because of my q's on ? I'm not a kid, or a nympho, u can tell by my q's, yet, he says I should marry. I've made the first happy through my writing, so now he wants to make me happy by coaxing me to want to re-marry? Honest answers pls, thanks.
