Blisters under penis, never happened before

I recently had sex with my girlfriend without protection, as i have been for the past two years and have had no problem. Although yesterday, she was a bit dry so she put some lube on me, not too much. When I inserted, it hurt me and her a bit cause it was really tight and she didn't put enough lube. Fast forward to today, i wake up and pull my foreskin back and there are blisters covered with white stuff on top. I was able to wash it off, but the blisters are still there.. This has never happened to me before. Am i showing symptoms of genital warts? I have had other women give me oral on other occassions, but never sex without condoms. I've attached some pictures, please help me out, thank you! They do not hurt or itch, just stress the hell out of me!

Looks like friction trauma to me. Have a break from sex or masturbation for a week. Should heal itself.
