How do I tell him..

So I’m coming off my period and occasionally I’ll get a UTI.. and I did this time and my bf is in town.. how do I tell him.. I feel so disgusting and embarrassed... help 😭😭

UPDATE: I told him.. but I was so nervous I ended up crying on his shoulder while telling him and he just held me and was super amazing about it, now we are vacating on the beach :)
