Hi, just wondering, 2 weeks ago both of my testicles have or feel as they have enlarged (no pain). went for a testicluar ultrasound and they couldnt find anything which is strange. Just wondering what have caused this enlargment? and penis feels drippy after urination may probably be from a virus. im just wondering where can this virus come from and how to prevent it in future. could it be from food, drinks? or masturbation or general hygiene issue?. thanks.
