Iron Bull is an omni-sexual into some disgusting ****... **** him.
And keep in mind I don't want nor need gay LIs, if for example the only LIs in DAO were Morrigan and Alistair (they were the only worthwhile ones anyway) and Riordan, an NPC, was gay I'd be perfectly cool with it. The thing is, no negative/humiliating stereotypes.
Okay, you might disagree with the partners he's chosen in the past, but he's still a stoic persona. And also with sexuality aside, the main difference between the two was the the Iron Bull was open – as he could for a spy – where Blackwall wasn't, at all. Even when chasing after Josephine, he's closed off. And they're both jovial, though it takes pairing up with a fellow rogue to get Blackwall talking.
Iron Bull falls into the promiscuous bisexuals tropes. There's one in every DA game, making it seem like they're promiscuous because they're bisexual.
Well, i agree with Hanako regards to the sexuality, he's a pansexual. Back to the personality though, he's still stoic. And while being promiscuous might seem wrong in this is society, this is only because someone who's not white, male and straight enjoy having more than one partner in a short period of time. Which is funny because neither Isabela or the Iron Bull mention having partners recently in the games. The only reason i could see Isabela be called such was because she cheated on her husband, who was a bastard, and required a friend to finish him off so she'd be free (Zavren, which i didn't find out until my recent romance with her and going through all the dialog options).
