Please help! :(

Okay so is there a such thing as a friction rash/burn from having sex (located on a mans shaft) while I'm dry in my vagina? My boyfriend really wanted to have sex but I wasn't completely lubricated down there and now he has a small rash/burn on his shaft? It looks a little red or irritated and little itty bitty bumps, neither one of us has an std or anything like that because he was a virgin and I've never had anything like that before. Any help is much appreciated, it normally goes away after a couple days of not having sex, but I wasn't sure if this has happened to other people?? Feel free to comment and leave  thoughts! :(
