Sure not inherently a bad trait. But let's just be honest here. It overwhelmingly manifests into a very narcissistic personality type and that isn't good.
There’s of course nothing wrong with a bit of thirst-trapping. But when you’re supposed to be a “legit actor” yet you’ve made everything about your identities, sexuality, thirst-trapping, attention seeking- it does feel incredibly narcissistic and cringe-y.
It also doesn’t help that the people who still mostly pay attention to Nico and who are the primary target for their thirst-trapping are queer males who are unabashedly into guys. Yet, Nico spent years shitting on the “gay” identity, years using queers for photo ops and interview opportunities, years using “queerness” for attention while also still coming off really insecure and gay-panic-y- it does add another layer of cringe and coming off leech-like.
As I’ve said many times on this forum, there are a lot of guys who have a difficult time dealing with their dimensions, fluidity, traumas, mental health struggles, drug dependence, insecurities, trying to understand the gender, sexual, affection, romantic, emotion, relationship, commitment spectrum. But most of those guys don’t also constantly seek gay attention by thirst trapping and don’t constantly use “queerness” for publicity at the same time. So, that does especially make Nico come off narcissistic and potentially toxic.
