I don't really see an issue, here, neither with discussing contraception with male coworkers nor giving condoms to coworkers, male or female. I mean, I can see how people would see an issue with it, but I've worked in an unusual work culture (healthcare/emergency department) for 15 years--we discuss things with each other that, when I talk to my layperson friends, I realize aren't usual topics for coworker discussion, lol.
