Hi. There can be slight bleeding (the orange-pink vaginal discharge
that you have described) after coitus, and there can also be painful urination (because of urethral trauma). But what is more worrying is the pain that you are experiencing. I would advice you to consult your Doc, get a urinalysis
done and rule out Urinary Tract Infection
. If confirmed a course of antibiotics will essentially cure you. Take Care.
