Sex after baby. It’s been 5 years...

Hi ladies, I started seeing a guy and recently things got intimate, not fully. But it’s getting there. I had my baby 5 years ago and haven’t had sex since then. I’m terrified lol it’s like I forgot what I’m doing and I’m scared I’m not as tight anymore. 😔 but then again nothing has been in there for 5 years 😂 any suggestions on how to over come this fear? I’m just not as confident as I once was before 😐
