I’m scared to let him go down there🙈

So this scared feeling has been going on for the last couple of years.. I’ve only let one guy one time go down there and it was about a year and a half ago. I don’t know what it is but I feel uncomfortable with him down there, I clean myself regularly and I always keep up on my shaving but I always feel like I’m going to “taste” bad or not smell like roses so I don’t let him. I don’t know if I’m all alone in this situation or not but I neeed advice. I really liked when this other guy did it but I was also still scared the entire time.
