safe?

So my fiance and I tried to have sex last sunday. he peed right before we tried, he used a condom but he started to put it on backwards and realized and switched it around and put it on the right way. not sure if it touched the head of his dick or not but like a said peed right before. it wouldn't go all the way in just the tip and he didn't cum in me. were we being safe? I'm old enough to have sex I just become a worry wart when I do which means I should probably have waited but oh well.
