Marvel's first 9 gay kisses (plus one honorable mention)

I was inspired a while back to try to figure out what was the first gay kiss shown on-panel in a Marvel 616-verse comic book, and that in turn led me to collecting a list of 9 gay kisses to date. My criteria were as follows;

1. That the kiss be on-panel
2. That it be lip-to-lip, and have either an implied or blatant sexual/romantic/erotic element to it
3. That it be between two members of the same sex
