I'm nervous and embarrassed

About a week ago I noticed a few little bumps in my vaginal area. I didn't think anything of it because they don't really bother me but the more I read up on HPV (genital warts), the more I think that might be what it is. I scheduled a gynecologist appointment and I go in on the 17th, but I've been thinking about it 24/7 and it's driving me crazy. I know it's a very common thing but I'm still embarrassed and scared. I'm in a serious relationship and I think that's what is bothering me the most. I don't care about me, I'll be fine after I go to the doctor but I'm worried about my SO getting the virus also. I'm sure he already has now. If I find out that's what it is i don't know what or how I'm going to tell him. And I'm scared we'll be passing it back and forth forever. I guess I'm just looking for some words of wisdom and comfort. Thanks..
