I definitely get this. Generally while I may or may not be situationally comfortable with a straight girl grabbing my chest, it is rare that it makes me feel threatened. In general, it is my personal form of sexism that I will always be threatened more by unwanted male advances than unwanted female ones, and will never shrug off male groping the way I do female groping.

Knowing that I have probably groped you (and I mean kdsorceress, not you "lj user="tirerim">) in the past, since I'm known to do that sort of thing, I very much apologize if I made you uncomfortable, and I will refrain from it in the future without first obtaining your verbal permission. Though I will not retract my opinion that you (again, kdsorceress) have extremely nice breasts.

Love,
Herbert.

P.S. You (both kdsorceressand tirerim) have standing permission to grab my breasts when not vastly situationally inappropriate.
