Anyone else have a hard time orgasming with a partner?

I can get myself to pretty fast when I do it myself but once someone else is around I get self conscious and then I just can’t. It’s like I get nervous that I’ll take too long and once that thought pops into my head I can’t get it out enough to cum at all. Don’t really know how to fix that since I’ve always been very shy/self conscious when it comes to sex.
