What should I do?

My boyfriend & I have been together for almost 4 years now. when we first met, i knew he was a freeeak 😍 but he has never really tried to do anything kinky with me. He loves when I scratch & bit him, & i like anal, being choked etc. Well for awhile now, ive been wanting to try new things, but im kind of "shy" & dont want to bring anything up & it be awkward (yea i know, 4 years, ha what could possibly be awkward) haha so what should I do? im talking whips, bondage, etc.
