we've done this before too.actually, sorry if this is TMI, but i think that's fine too - with a tampon in so just clitoral stimulation. i am ultra sensitive with that during my period and it's a very different/strong orgasm.Sounds like it is a mental thing mostly but if the guy doesn't care why not? I mean it's not like you are asking him to "go down on you" during that time of the month. I have noticed that orgasms do tend to be bigger during that time of the month or maybe it is just me. Anyhoo, to each it's own. If you can wait then wait if you don't want to then don't.
