Go for it
while it doesn't lead to direct sex, you can also do a massage thing for him
If I remember correctly, it involves footjob stuff

I have finally got to those scenes where the mc/captain and Katari get to massage each other, they do achieve sexual satisfaction from the erotic massages.
It is ludicrous and quite dismaying that Katari and the mc/captain are still not going all the way and engaging in full sexual activity.
Katari has stated that he refuses full sex with the mc/captain out of respect and that he is a subordinate lowly mechanic and yet Katari agrees to erotic and sexual massages.
Katari is exceptionally well endowed and he may be concerned the mc/captain may be seriously injured if he tries to top him.
I finally got Katari to have full sex and bottom for the mc/captain on that Sithyryan beach, it helps to have your mc/captain set be a dominant/top in the settings.
When you get to the beach in a drunken state Katari will resist bottoming and protest. But he will do it if you insist and not like it.
It becomes obvious Katari is frustrated due to being abused and dominated all his life, he can only truly assert a degree of power during sex which is why he often becomes aggressive sexually and doesn't like bottoming, for Katari bottoming is a form of being subjugated again.
