>>41442If someone is too crazy for you - don't ever stick your dick in.
Don't fuck anyone who you can't imagine having at least short term relationship with. Be wise, its fun.
Also, think about which kinds of craziness are okay with you and which are not. You might find yourself in a fun position, actually. Sometimes you could marry someone who's considered bonkers because she has all the traits you care about or you'd stay a mile away from someone who's considered normal cause she has traits you'd have severe issues with.
