Today I Learned, my dad likes Beastiality. But that's just the beginning of my story and I don't know what I think anymore.

So reddit, I think context might be important here so we're in for a bit of a story. I think I need to tell someone. (tl;dr at the end)

I am a 20 year old male (21 next week) and I have a crippling emotional problem with sexuality. I am gay (I think?) But have been completely publicly sterile and asexual until only just recently when I met an awesome new friend about 4 months ago, so far he is the only person who knows that I am not straight but I'm not even comfortable talking about sexuality with him. Despite being my closest friend, I don't think he could define my sexuality or even accurately guess at it. I don't know, or remember why, I feel this way about sexuality and I don't think I want to remember.

I am frustrated with myself for containing every emotion and feeling I have felt since realising my sexuality and have struggled to be comfortable with who I am. So instead I have become an extraordinarily good personality mirror, I can emulate most people and make friends with anyone, a great skill but it has dissolved my already repressed personality.

Before today I would've described my parents as amazing but slightly annoying as all parents should be. They don't know about my sexuality and they are very supportive, never really asking questions about any love interests as some people seem to think is appropriate for 20 year old males. They provide excellently for me and my older brother, they pay my rent and petrol to allow me to study at a university out of town and they allow me to stay at their home whenever I like.

My dad is close to 60yo and is a successful senior manager in a successful multinational business (hence why he is able to provide for his family well) and he works hard but is close to retirement. He works interstate most weeks flying out Monday and returning Friday. Despite this we are very close. We own and manage a small Farm together, we have good common interests although these are naturally decreasing as I gain independence and become more busy.

Anyway, today was somewhat unexpected and traumatic for me. Christmas Eve began and we were having family over for the afternoon. Dad was selecting music to play and as always he decided he would give me a lecture on good taste in music. He currently is obsessed with a song, which recently had a popular revival by David Guetta, but my dad clearly loves the original by Nancy Sinatra. During our discussion he decides he wants to Google a list of the different covers, parodies and remixes. So he grabs he laptop (which he takes with him interstate and is full of crap so lags like crazy), opens Firefox and goes to search "Bang Bang (my baby shot me down)" but naturally his laptop lags after he types the 'B' and deselects the search box on the Firefox home tab. In the suggestions box was clearly written, (along side other dad-like searches beginning with B) was "Beastiality" and "Beastiality xxx" and "Beastiality video xxx".

Thankfully my dad is not particularly observant or tech savvy and is not a touch typist so he didn't see these unfortunate words or more importantly know that I had.

My first reaction was to laugh, I didn't but I wanted to until the shock hit me or the realisation that it was my father. I don't think I am naive, clearly spending weeks away it wouldn't be surprising if my dad was a regular on Internet porn sites.

My second urge was to get access to the laptop later and look in the history and system registry and see what else he may have seen. Clearly I don't want to do that though. The day then continued and I continued acting as I always do.

Tl;dr; my father had clear searches for Beastiality in his Firefox suggestions bar which I saw while he was using the computer but he didn't know I saw. I don't know what to think.

So reddit, am I supposed to be/allowed to be shocked/horrified/broken by this or is this just another artefact of being fragile emotional crockery when it comes to sexuality? I don't know how to feel about this anymore. Should I be worried about my family or just do what I always do and sweep it under the carpet, forget I saw it and move on?

EDIT: Grammar, clarity
