With a beautiful woman. The where isn't really so important after that. But the bedroom is a good start. Or the kitchen. Or the patio. Or an out of the way janitors closet. Whatever works.
Anywhere I can be that won't offend this generation of cry babies. So I keep it to my house and property, nude beaches and nudist resorts
honestly, I'd have to say 'in a hot spring surrounded by snow' but not alone. I'd like a nice girl with me.
I've never been in hot springs but that would be my guess for what would feel amazing next to being in bed with my love.
