Being vulnerable..

Te
I have a problem with being vulnerable. Just letting myself go towards my s.o.. We talk about it all the time and I open up but I feel so insecure about my lady parts. I have a problem for when he sees my face when he gives me pleasure. I feel like I'd lose power or something? Like after he's seen this part of me I won't ever be able to go back to being careful with my heart because he's seen the full me. I want to experience true pleasure but I can't ever let my wall down.  Does anyone else struggle or have struggled with this?
