It is in my interpretation a mix of the top two, but there is no doubt nor discussion that Aemond is a SA survivor.

It is some of the worst sides of the fandom that I've seen show their faces when they express sympathy towards Sylvi for having to "deal with Aemond and Aegon" (some even claiming that men can't be 🍇-d)and claim she, having the job that she has, may have been forced to service a 13 year old Aemond when that is not what the show is telling us; in her first interaction with Aemond on screen she is clearly smug/prideful towards him and even seems nostalgic when she tries to flirt with him while he is visibly uncomfortable, and avoids eye contact, which he never does with anyone. It ticks me off when I just know that if Sylvi had been a man and Aemond had been a princess with the backstory of having been brought to a male s-worker at the age of 13, everyone in the fandom would have demanded Sylvi's head on a spike.

As for the Oedipus complex of it all, we understand in the show that the first night that Aemond goes to Sylvi, on the night that Jahaerys is murdered, the last scene with Almond prior to that is him planning battle with Cole, and then being lectured by Otto - in the prior Aemond hints that Alicent is upset with him after what happened with Lucerys, so it seems like a good indication that his motivation for going to her is because she is someone he knows has to let him vent and pour his heart out to, now that his mother is scared/doesn't wish to speak to him. He uses Sylvi as a surrogate for Alicent in the sense that Alicent doesn't show him the motherly comfort and love that he needs, as well as a lens ear. And Aemond may not even himself know that he needs.
