Extremely shy to hit on guy (fuck buddy)

We’ve been fuck buddies for a while now and he’s VERY upfront and just has an over all out about personality. Literally has no self doubt very confident. This is why he always initiates our fucking lol. I never do. My hear starts racing , I’m shy , I’m afraid he’s going to say no? Which literally NEVER happens. He always wants to see me. How do I get over this? I haven’t seen him in a while and I want to fuck.
