Open Question: How do I get boyfriend to spank me?

[feedcrawler]

We've been together for over 13 months, so we know each other well. but we started doing sexual stuff the 11th month, because I used to be trying to be part of a religion that I realized I don't believe in. Anyways We haven't had sex, but we do sexual things. And I do things to please his foot fetish, but he's too afraid to spank me, even though over text he's said it sounds really hot. How do I convince him to slap my ass? He won't even do it in a casual way, let alone in the full-on over the knee way I want. He even promised he'd slap my ass the last time I saw him, and then he said he was too nervous I'm 15 by the way
