Let me break this down for you.
First of all, even IF they (SHINee) had sexual intercourse, they can't physically have kids. So, for you to have what you want (which is the procreation of homosexual babies from two males), they would have to adopt gay children instead. But they can't MAKE them.
As well, two straight parents don't always yield heterosexual children anyways. That goes both ways (like bisexual people).
Please take a biology class. Didn't you have to take sexual education in elementary/high school, too?
I know we don't offer insurance around here, but I sure hope yours covers the fact that I just blew your mind.
