>>120217057That fusion was very overtly sexualized between the exposed muscles and body hair, the focus on his sweat, the bulge, and the hip thrusting, so can you blame people who feel uncomfortable by it?
Fusion is made out to be an intimate act of love that requires sexy dancing in the early seasons, with the added fact that sardonyx, malachite, and the forced fusion experiments all had very rapey overtones, if the writers didn't want people to associate fusion with sex only after Steven started fusing they did a bad job of retconning it.
