I have found, and this is just me... that I like it under the right circumstances. An example... one time I was with a woman who said she really liked snowballing and wanted to do that with me. We did it, and it was OK, wasn't gross for me... but it sorta felt like the real objective was to get rid of my cum... and having it treated like poison isn't that much of a turn on. But in another setting, I knew a woman who loved kissing after oral with my cum still in her mouth, and while plenty of it ended up in my mouth, she was pretty enthusiastic about getting it all back, often reminding me verbally that she wanted it all back... and in that context, it was mighty hot. So for me it's a "just depends."
