Depends entirely on the alien! I have, multiple alien species, and their interaction with humans varies from each species. (and of course, all aliens themselves are different) Some have been long since adapted to humans, some are newer to the intergalactic fold and have interacted with them less. Humans are not particularly rare, nor do they take a majority in the populous of the connected planets/stations. (though as a side note, my current role of humans aren't as significantly prude as we are now, but they do still culturally try to keep sex separate from the public and this does play a role)

Vazaroust's species, Rnjaut, is a little more secluded. He's unusually involved in other aliens much more than most others of his species. They don't have a lot of intergalactic presence due to a combination of personal preference, and complicated adaptation. (Vazaroust has to have most his skin covered if he's out in the sun on most planets, as his home planet doesn't have near the same level of UV exposure as, say, Earth does) They tend to keep to their own species or other blind species due to their being more in-common with communication styles. Humans aren't regarded with any specific difference to others for the most part, they kinda all get thrown into the same pot of 'small, sighted species.'

The Gesierdre species is one I haven't drawn much but I've developed a bit. They operate on an extreme sex difference, multiple males per one female, the female giving birth to hundreds. So all other species that have single pair are either extremely confusing or extremely fascinating to them, Humans included. Most of what makes intergalactic travel are the males of the Gesierdre, so their interactions with humans tend to be uniquely one-sided. A lot of them appreciate Human's tendency to have a high sexual appetite as they make for compatible partners when they're not at home for the breeding season. They don't appreciate some Human's tendencies to be clingy and apply human-style coupling off relationships with them. They also don't really understand the function of human sexual attraction. Because they specific 'sex for pleasure' and 'sex for reproduction' cycles they don't get any species that is able to do both. And this is before even getting into how humans everything functions in contrast to their own. But this would also apply to any other species that doesn't have the same sort of colony reproduction structure they have.

Tevejya's species is still getting felt out and I think they don't regard humans as being particularly remarkable in any way. And I'm still developing Udaesnmocris and Sikarien's species.

And then I have all these unnamed species.

One is a largely sexually open species, sex and intimacy is wrapped up in their media and their culture, they don't have the same need to hide it like humans do and find the fact that humans are so hellbent on having sex in only certain designated areas, very strange. They understand general politeness and consent, they just never developed that tendency of obfuscating when sex is on the table. They also don't really communicate via facial expressions, they're much more action/touch/vocalization oriented so there tends to be a disconnect in grasping human facial expression based communication.

Another species had the side effect of, due to their location and placement in the system, ended up getting some human transmissions and broadcasts that had some influence on their culture, but not and overwhelming amount. So they bare some similarities but most their species is matriarchal and egg-laying so they don't have the same sort of family structure.

And another species I'm deliberately obscuring for Reasons, spent a great deal of time with humans, centuries, so they have the most complicated relationship to them along with personal resentments because of past conflicts with the humans. They are frustrated by some more narrow elements of humans, their perceived entitled-ness, their obsession with requiring clothing and covering even after all these years. But they also find human's smallness and softness compared to themselves, novel.

There's a lot going on and it's really difficult to be brief about everything so if you have any specific questions feel free to ask, or even DM me.
