It is somewhat similar for me. I love cum and I found out it almost does not matter which penis the cum comes from. But I do not like the rest of the human body in contrast to animals, ideally I only want to see the penis. Moreover after trying some sex IRL with a guy I found out it is not what I like. The smell of the human body is unattractive, the taste of human cum is appalling, the texture of cum and penis is surprisingly
not dog-like.
So I still consider myself zooexclusive event though I occasionally enjoy some cummy dick pics.
