Sounds like we pretty much have the same attitude towards spirituality, Raja. So naturally, I think you have the right attitude ;)
About fully enlightened people having sex, I'm not so sure. Of course, there's no clear definition of enlightenment but if you take for example
Theravada Buddhism's map of enlightenment, they map out four stages and in the third stage, the sex drive disappears.
I think this is the elephant in the room of the spiritual scene that so many people who think they're fully enlightened love to ignore. But I think it's right. In my period of "divine bliss" or whatever to call it, I experienced a sort of ongoing merging with the divine (sorry for sounding new agey), and the notion of merging with another human body wasn't appealing at all. I suspect that if there's such a thing as "fully enlightened", loss of sex drive would be an aspect of that.
But like with the bliss of oneness, I don't think loss of sex drive is something that should be pursued. That would just result in frustration rather than liberation.
