What Does Tingling On Tip Of Penis And Tip Of Foreskin Indicate?

Hi. I had unprotected sex on holiday. I regret severely. ... never done so ever. Now I have very slight tingle on tip of penis and tip of foreskin. No markings except one red dot. No pain whilst peeing Dont Notice A smell. Problem is I am married and wife wants sex but I don t want to until I know what is wrong....The woman I was with put some barrier liquid on my penis. ..... I was very drunk to be honest.
