Sulu was not and is not necessarily gay. He can be attracted to both men, women, bald aliens, and, why not, even shaved Caitian hookers if that floats his boat. In this timeline, if he has decided to have a monogomous relationship with a man and father a child then that is what it is (a long-overdue attempt to be inclusive in mainstream Trek and an homage to the original actor).
People can debate whether Sulu prime was involved in a long term relationship with a man if they like. There is little evidence onscreen to contradict this. There is little evidence onscreen to support this either so fans new and old are free to interpret it however they like.
As my mate pointed out long ago, Rand is so obviously Sulu's fag hag, he must be gay. What more evidence do we need?
