I think your fears are probably well grounded in most cases, however Bali is a different story as it's considered the "holiday island" of Indonesia and things are a LOT more relaxed there and a blind eye is turned to most gay activities ( as long as they dont rock the boat too much) but same sex couples etc are very much the norm and accepted there without any problem, Likewise the locals ( who mainly ARENT from Bali at all but some there from other Indonesian cities either on holiday or to work and as they too also realise that things are more relaxed there in relation to gay sex etc they then also actively go there for fun with Bules (white guys) too - hence the ease and availablity for fun should one desire it.
