What are these bumps or blisters on my penis? Std or maybe not?

I had these for about 9 days after sex. It was prolonged sex and the condom broke and continued to have unprotected sex for a moment. I immediately went to wash myself after and while washing it seemed like it was irritated a little down there. Before the day of sex I also masturbated a lot no lube. But the day after sex these bumps or blisters showed and are still here 9 days later. I haven't masturbated or had sex since because I'm trying not to cause further irritation and hoping they'll go away. Hoping it's just due to friction or reaction to the condom, nothing serious. There is no pain, and no itching except a little itch occasionally. No pus or anything associated with herpes symptoms so far. I told my partner about it and she swears she doesn't have a sti. I was wondering what you professionals thought about it? Any thoughts, diagnosis, or feedback welcome. Thanks
