如果我有戀足這習慣怎麼辦

Well, that's a big problem indeed

Sorry but i have to quote what the bible says
"to escape from that"
we are teenages and it's very normal to have this
this won't last for a very long time, cos we have a lot of thoughts in this "puberty", we think a lot about sex all the time and all sort of things but, we need to escape from temptation.

Try to keep your eyes up, don't look down, got me?

Doctors said that if your situation is "NO FOOT, NO SATISFACTION" you better go see doctors, they will help you but i think they will tell ya what i told have you

Escape, Escape, and Escape...

\This, somehow, is the only way

P.S Hey i got another suggestion, pull your eyes out...(joking)
