It is common for urethritis
to occur after the first intercourse. Pain occurs as a result of rupture of the hymen
. Itching could be due to the chemicals and the dilator used. You should take some urinary antibiotic and urinary antispasmodic and abstain from intercourse until the symptoms subside. If you have allergy
to local applications, use other methods of contraception
. Please consult your gynecologist for an examination and advice. Take care.
