What, pray tell, would anyone find "sickening" about an opposite sex pair of friends engaged in behavior typical of a married couple? There's an obvious lack of any reasonable answers to this inquiry, and a well-trodden history of people characterizing same sex intimacy as significantly less palatable. To claim otherwise flies in the face of very well documented history.
I characterized your comment as contributing to homophobic tendencies that are pretty well documented in our society. I made no assertions about your intent or personal character and did my best to gently suggest that thinking twice about the implications might be warranted. Nothing I've said even remotely warrants an apology, nor is one forthcoming. If you have a problem with that, feel free to reach out to moderators.
