Homosexual gay beastiality bondage rape fantasies

Please take note that I am aware that none of these should be confused or related to one other and that beastiality is the only one that is illegal in a lot of places. Don't attack a certain group just because you are offended by my sexual preferences. I might be the only person in the world this messed up, or I might be normal... I don't know. It's why I'm asking. Thanks in advance.

Fantasies:
1. As a man, woman or male furry, I am collared, muzzled, cuffed and shackled (with my legs and arms forced into a spread out doggy style position) to a prison bead where a man rubs his penis against my chest with the tip being pushed under my chin. His hands are grabbing my hair to pull my up and down. I am anally penetrated by either another man or a dog. If it is a man, my neck and my side are grabbed, if it's a dog, the paws are wrapped around my waist.

2. As a man or male furry, I'm in a similar position above except a woman or female furry is underneath me in a missionary position. In this case, I'm still being anally penetrated in the ways described above.

3. As a woman or a female furry, I have my legs tied spread eagle to two wooden rods that have the ends connected by a three inch chain to two metal hooks on the ground spaced four feet apart. I have a metal belt that has a metal strip attached leading past (but connected to) a metal collar and leading past (again connected to) a metal muzzle and connected to a 3 inch chain that is connected to a wooden post or a wall roughly 4' off of the ground. (So I'm spread eagle at a steep angle). There are two wooden rods that lead from loops on the sides of the metal belt to leather straps binding my elbows to my side leading through metal cuffs and connecting to a rope that leads to two tent spikes in the ground spaced far enough apart to make my arm position "fairy like". The reasons are to keep me helpless and humiliated. In this position a big cat vaginally penetrates me with the paws wrapped around my waist.

Sorry if number 3 is a little confusing, I tried to keep it clear, but images really are worth a thousand words.

Anyway, I can't help but feel like I should talk to someone about it, but I keep it to myself from fear of ridicule. I've tried using the fantasy labeled "2" and removing the anal and beastiality aspects of it, because I want a girl friend and I'm thinking it's going to be nearly impossible to find a low maintanence woman who isn't completely horrified by these thoughts, but I have trouble cumming without thinking like this. Is it a learned behavior that is simply driven by my hormones and upping the ante with the abundant access to porn or is it natural and permanently lodged in my head like homosexuals claim with homosexuality (I've thought like this since age twelve when I had horse riding lessons)? Also, why is there very little porn depicting bondage women with animals? Is it that abnormal?
