Sort of. I had a friend that I was worried about leading on, since the way she was acting gave me the impression she was kind of into me. More so when we ended up in a sort of platonic cuddle buddy situation, and I felt bad because I wasn't sure if that was her having feelings or just enjoying cuddling (which I was quite enjoying myself), and if I might be hurting her by letting it continue. Eventually, after I felt bad about that for a while, she cleared the air by outright asking my thoughts on what our relationship was (I was feeling like I needed to do the same, but she beat me to it). I said I didn't think I was interested in her as anything more than friends, she said that she would have been interested in more than that if I had been (though didn't feel like I'd been leading her on), but that she was very happy just continuing as we had been, and that was that.
And then three weeks later we made out and now she's been my girlfriend for three very happy months, because apparently I suck at emotional self-awareness and took far too long to realize how I felt. All's well that ends well, I guess.
Does that count as unwanted affections? Probably not, since it wasn't so much that I didn't want affections as that I was enjoying our relationship as it was and just didn't want to hurt her if she was getting the wrong idea, plus it turned out I did want the affections, but it's the closest I've got. Next closest would be suspecting somebody was into me, but nothing ever came of any of those instances.
