bloody mess-up

Anna
So I was with my boyfriend today, and he's an extreme virgin. (I was his first kiss). We were standing somewhere and he went to finger me, and he pulled his hand out and there was blood on his finger. (I got my period). He kept insisting that he didn't care and it's not bad, but I was just so embarrassed, and I hate thinking about it. Is there any way to redeem myself after that?
