friction burn, I think

last night my girlfriend was giving me a hand job and it was somewhat rough. anyways, an hour or so later she tried to give me another one but the tip of my penis was really sensitive to the touch and stung slightly when rubbed. there are no visible markings, today it still stings slightly when rubbed, though to a lesser extent, is this most likely just a friction burn? my paranoid, conspiracy theorist mind makes me worry that it might be an STI of some sort, though all the evidence seems to indicate otherwise, I was hoping for some alternative points of view on this

Hello,
These symptoms can be due to chafing or friction rub. You can apply some calamine lotion at the rash as it will help in soothing the skin. Also wear cotton undergarments. Application of mild corticosteroid cream and oral antiinflammatories like ibuprofen/acetaminophen are also helpful. Also use good quality moisturizers on the skin of penis to avoid any dryness.
