Non penetration sex tips?

Next Monday, my boyfriend is leaving to go to Europe for a little over two weeks. This is our last week together, and that really sucks because i’m on my period all week 😩

I want to sexually please him a lot this week because we won’t see each other for a while, but my period is too heavy to have period sex without making an absolute mess. And our height difference is too significant to have shower sex.

Is there anything interesting we can do or try out this week? Like any bj tips or how to have period sex without such a big mess??
