Make out on your period???

Okay so I'm young and new to dating & me and my bf have been together a short time. We've taken things slowly but more recently we're ready to step it up!! He wants to make out (nothing in the penetration side...just kissing and grinding/dry humping) on our next date...but I should be on my period!! So can you dry hump/grind on your period with a tampon in??
