Hi, Eruption on penis head after intercourse could be fungal infection , would suggest you to clean the part periodically and if possible get yourself examined.
You can start with sulphur 30, homoeopathic medicine twice in morning for three days.
Let me know after three days.
Please feel free to contact me if you have any other doubts.
