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.
