Condoms are they meant to reach the end.....please please help

I am super paranoid about STI's / STD's. I went to amsterdam a few days ago (heart broken from breaking up with my x) and for the first time in my life (with much encouragement from my mates) I overcame my fear and had sex with a prostitute.... one problem,

Whilst I made sure I didnt kiss or touch her and wore a condom at all times, I noticed that my condom was around1.5cm away from the base of my penis (ie did not reach the end) .... now im really worried, my friends told me I have nothing to worry about as I wore protection and the tip of the penis is the most important bit and I dont have any symptoms..... do I have something to worry about??

Please could a medical professional or someone in the know help me out here, being sleep deprived is no fun...

Thank you for taking the time to read this

You can get some sleep again because your friends are correct when they told you as long as the tip,head of the penis is protected then your fine.No risk and no testing required.Stop stressing,get some sleep and take care.
