As I recall, the sideline reporter on the ESPN broadcast said that the ref told her that the first technical was for excessive complaining and the second technical was for not stopping with the complaining, so not actually for any physical contact such as possible hand-genital interaction.
So, the story is what amounts to a double technical, I suppose, on KG and Frye plus another technical on KG for keeping on with his mouth. Plus technicals on various Celtics players for getting involved.
If that's the refs' explanation, that's really not something you can prove or disprove by re-watching footage, but you shouldn't really give a technical for more complaining before signaling the first technical for complaining. And technicals for complaining should be preceded by a verbal warning unless you do something like direct profanity at a referee.
