Is it safe? I know this sounds crazy!

Me and my boyfriend plan on losing our virginity to each other. And he said he wants to pull out. And he said he knows when to stop before he cums. And the thing I'm worried about is that even tho we are both virgins, can STD’s or STI’s still be a concern. I trust him, but that is my concern. Can someone give me info! Please!
