My Biological Father

So my parents had me with a sperm donor my mom is my biological and my father isn't but he's just my father. They never hid it from I've known that I came from a sperm donation since I remember myself or since I was old enough to understand what it means.
My bio dad is not a stranger to my parents they chose him as the donor. And they never kept him hidden from me I had met him since I was young. He is to me kind of like those distant relatives you've only met once at that wedding you went to. Ηe lives far from us and we only see him a few times throughout the years. And whenever he visits our place it's not specifically for us but for other reasons he just lets us know he's in town or something. But we don't really have a close relationship so I don't really see him as my father.
A few months ago while he was visiting our town I met up with someone on grindr (which was him of course) to give a blowjob both of us faceless profiles. We were pretty worked up and he was my type with a nice looking dick. He asks for a face pic and after I send mine he sends one back. After a while he sends "Well I guess you already know where I'm staying if you're still up for it". So I went to his place and sucked him off. It didn't feel weird during or after.
As I said since we don't really have a familial relationship it didn't feel taboo. I would feel a lot weirder if it was an old teacher or classmate, or coworker or something like that because these are people from my daily life.
After that we met up a few more times and whenever he's in town. He's even fucked me a couple times. But all of our meet ups are like any other grindr hook up: you meet up you fuck and just leave there's not a lot of conversation or hanging out involved.
To me this isn't a kink-fetish because I'm not particularly turned on by the fact that we're related and I wouldn't even call it i****t (I know it technically is). To me he's just a physically attractive older man (I may have a regular "daddy" dilf kink) who I trust as regular hook up (at least for when he's around which is not often).
