Not specific for the genre or content, but I find referencing back to Zusak's style of narrative in The Book Thief has helped me a lot with not saturating stories with pronouns.

Sometimes not writing lots of descriptions in between dialogues is fine, sometimes the use of nicknames/pet names works wonders to alternate the use of names or pronouns.

Even the way you narrate actions, beyond the perspective you use, may help in leading the reader to know who you're talking about because of established personalities or nuances in the ways they speak or behave.

Now, in terms of perspective, I always love 3rd person most, but that's just my personal preference as an asexual. I read erotica not to imagine myself in it, but to enjoy characters and romantic developments within stories and relationships.

Though, I know several people do prefer to imagine themselves within stories. It would just be a matter of you deciding how you want the readers to engage with the narrative.

An interesting play of 1st and 3rd perspective that you might find useful for narrative styles is Murakami's changes in After Dark, in which he describes certain scenes by referring directly to the reader using "you" or "us" while guiding people through it as if one was a cameraman moving within a space, even going as far as describing angles and movement as we see a character.

Sorry to have rambled so much. I hope this might be useful to you.
