Brief Answer:
Diclofenac with serratiopeptidase, apply cold

Detailed Answer:
Hi
Welcome.
I have gone through your query.
It looks like there has been a mild trauma to your scrotum. It could not have been because of the intercourse per say.

I would suggest you to abstain from sex until you recover, wear boxer shorts instead of tight briefs, you could use a drug like diclofenac with serratiopeptidase to bring down the swelling, apply cold pressure to the swollen area.

If the problem still persists even after 2 days or is increasing in terms of size, pain, temperature please consult a general surgeon immediately for a scan and further treatment measures.

This provisional advice provided by me is based entirely on the input provided to me. I would suggest examination by the doctor.

Hope this helps.
Take care.
