about a week ago i slept with my new girlfriend, we have not yet had sex, and this night we were 'dry humping' i guess, without using protection.the day after i noticed a red blemish on the glans of my penis which appeared to be dry skin and was slightly more red than the normal skin colour underneath this dry skin.a week on its still there and im worried it might be something more serious looking around the internet for different explanations proved misleading in some cases due to how symptoms are described.i'm hoping its just skin irritation thats taking a while to heal, for now i have applied germolene to the blemish and will see what this does.any suggestions to what this might be would be greatly appreciated, thanks.
