especially issues involving the opposite sex...

an older brother or sister would've been awesome for that.

I can't talk to my parents about that (well, I could, but talking about parents about how to manage your flock is awkward). Friends, yeah. But, man, having a sibling on deck for these times seems like it would be hella clutch.

This is perhaps the only time when I envy all of the non-only-childs out there.
