I havent had a STI test in ten years due to HIV fear. should I get tested for new partner? 

I'm a 33 years old straight male, I've had 10 to 15 secual partners. 
I'm worried I've got HIV. Havent had a test in 10 years due to worry of testing and finding i have it.

My new partner wants us both to have a test in our new relationship.
I like her and I'm worried I have HIV.. should I be worried as symptoms are usually not shown?
