I admit that fully fursuited human is more visually appealing than a regular human. I have seen several videos on youtube of someone in suit later taking off the head. And up to the moment of taking it off, they were kinda appealing. But the human below spoiled it.For me it's not the suits themselves that would be the issue there, it's the lack of tactile sensation, being able to feel the warm fur of your lover against your skin is part of the experience. So cold lifeless fake fur even if you could feel it through the suit your wearing yourself seems just unappealing. Then there is the issues over genitals not being the right shape, or extending far enough out of a somewhat loose fake covering in the case of male anatomy. As a furry the mental image of having sex with a full sized anthro was very hot. but the first time I actually saw a video of the reality involved, I just said Nope that's not for me. That said if people are into and enjoy it, all power to them. It's just not my cup of tea.
When it comes to sex. I am a smell based zoo and unfortunately I can not stand human smells. We are the only species that in fact smells so bad to each other that we have to actively mask our smells with chemicals.
Pretty bad and now add a hot suit that feels like wearing a sofa.
