Draft Lottery

My friend and I were talking today about how soon there is going to be a need for soldiers and how this time it's going to be men and women. Just felt like talking about this. It went something like this

Lex: I think I'd rather go to jail than to fight.
Me: Yeah, I would defnatly never be able to kill anyone
Lex: Yes you would
Argues about my sadistic tendencies for next 20 minutes
Lex: Fine you wouldn't be a good soldier
Me: I think I'd just mention I'm Bi and get a dishoranble discharge
Lex*laughs her head off*

Imagine if we did ahve a draft lottery. Only straight people can be in the army *Don't Ask, Don't tell* or you can't let others know.
All us Gays and Bi would be the only ones left. How the fuck would we procreate.
Whatever.
I'm bored and felt like talking about this

Thoughts on the draft. What would you do?
