Why is he like this? He's very odd?

This landlord who I just moved in with is very odd.

I met him through a friend. He's very nice, understanding, and very easy going. He owns a couple businesses such as coffee shop, art gallery, and other things. He's also very well known among my circle of friends. I really like living with him so far.

Especially how he's so not homophobic and is really cool around some of my gay male friends. He even point out which guys look good once in a while. Also he's not a pervert when it come to me being bisexual.

Many of my friends often comment on how gentle he is when he shake their hand or hug them. He also have a couple pets and let me have my dog. He's very gentle with all of them as well. Other thing that is unusual is, he's very humble as well. No matter how much we compliment him, he never seems to get excitied. He always say "thanks" or "I try" or something along those line. Also he have one wicked sense of humor and laugh at almost everything which I really like.

What really

surprise me is, he used to be in military special force, have done military contractor, have been a kick boxer and boxer, and have lived in couple different countries.

I have heard from a couple female friends that when sleeping with him, he like it when girl scratched him to point where he bleed or bite him until he's bruised or even use razor to make him bleed and drink his blood.

Another roommate also told me he have a couple weapons locked away in his bedroom as well.

I don't understand how could he be so gentle, calm and humble but at same time be so maschoist/sadistic, have done so many things that give him every bragging right for many things, and other odd thing that totally contrast everythig?

don't try to understand what you don't understand
