Dear sir,
Thank you for your query at DoctorSpring.com
You seem to have bruised your tissue because of frequent intercourse and that is causing the dripping of secretions from urethra. You don't need to do anything and avoid intercourse for a week or so and everything shall become fine. However if you don't improve even after weeks rest then you should get investigated to rule out infection.
Take care
Sincerely
Rajiv Goel
