Cold sores and oral sex

[mushaboom]

I recently had what I believe was a tiny cold sore in the crease of my lip. I'm prone to them and usually they get fairly large and will take a week to heal. But this one stayed tiny and scabbed over quickly. I made the mistake of forgetting about it in the heat of the moment and gave my partner oral sex and we then had unprotected sex.

I noticed a few hours later that I felt a very tiny blister was forming. It's been a day...and it hasn't gotten bigger and I haven't noticed any tingling...which I normally do with cold sores.  But i'm now worried that I may have infected my partner with genital herpes and possibly myself because we had sex. I'm not really sure what to do. I'm not dating him...we're only good friends who sometimes sleep together. We usually always use protection...but didn't this one time.

What are the possibilities that I may have infected him? What should I say? I'm really worried and embarrassed I may have even put him and myself at risk. I can't believe I didn't even think about the fact I was getting over a cold sore. I'm usually very careful. Should I wait for any symptoms or if he mentions he's noticed anything? I don't have any health insurance right now and am overdue for my yearly exam with my gyno. Should I go to the health clinic just to be tested and make sure? I was planning on going soon anyways just for a checkup.

Any advice would be appreciated. I'm very concerned about this.
Thank you.

I don't have any form of genital herpes. I was tested in May and didn't test positive for anything.  I do have HS1...the type of the virus that causes cold sores...but so does a large majority of our population. Whether or not they actually get cold sores depends on the person.
