Where can me and my gf go to be alone? Both our moms dont work, and are always home?

I'm assuming that you are wanting 'alone time' is referring to sex because of the 'having a bed would be ideal' statement.
I cannot condone sex acts, personally... and I'm definitely not your mother(s). My suggestion is a friend's house or the back seat of your car that you drive. Those were my options while I was growing up. Just remember to have a little respect for your girl. Best wishes!

this is difficult but if you have a large basement with couches and maybe a tv, that coul be good :)
