So I take my pills sublingually, as one could probably gather from the title, and I'm curious about how long the estrogen hangs around in my mouth after that. My boyfriend is an ftm guy, and it suddenly occurred to me that I don't want to get the wrong hormones all up in his system when he kisses me! D: As long as I wait like, fifteen minutes or so after taking them before mackin' on my man, everything should be aokay, right?
