Yes to both questions. As long as you don't die. Because as we all know those that are resurrected will be like angels, without sexual organs; thus, the third sex.
Just be careful who you marry, you will be stuck with this person to all eternity.
When you think about this, it is just one more reason to say the whole idea makes absolutely no sense.
I was told that in the new order we will maintain the countenance of a 30 year old. So if we have sex for eternity, we will be having children for eternity? And our children will have children and their kids and so on. I think we will all find a limit to this concept of infinity very quickly. I also think those resurrected without sexual organs will be highly pissed off.
But let's see. We need to get past Armageddon to figure out the rest. So, when is that happening?
