I'm a pretty straight and narrow person when it comes to drinking and smoking. I'm willing to drink socially and smoke occasionally but for the most part they aren't really in my life. I have a girl that likes to drink and smoke and find nothing wrong with it. As long as she isn't forcing it on me and it isn't affecting our relationship I'm cool with it.
As for the foot thing, there's lots of guys that love feet but they afraid to admit it. I don't see it weird or awkward at all.
