No, it would make Ra's no longer straight, but not gay since he had shown no interest in any other men his entire time in her body.
>>112806541I believe it was implied the pits were a scarce resource in BTAS and that most of them were destroyed or overtaxed (somehow), so only Ra's knew where to find the remaining. Bruce also didn't trust he wouldn't slowly lose his mind from its repeated use same as Ra's. And given he slightly went manic the first time, and Ra's was lying about several things it's likely that would happen.
Bruce also saw what use of Venom did, so he was likely wary of prolonged doping.
