SO Watching Procedure

Allie
Has anyone had your SO with you throughout a surgical procedure? If so did they ever share their feelings about the experience afterwards?
 I am almost 8 weeks, getting suction aspiration and I have the option of a support person being present and my SO will be there. I have anxiety about my appointment, and will likely be awake, just sedated.
 If I was in his position, I'd probably be really uncomfortable, and I'm feeling nervous for what he may..see? 
*Sorry if this is an inappropriate question to ask, I'm new.. If there's a better or more appropriate group to post this in please let me know. *
Thank you in advance
