So I had a bit of rough sex. and at some points, i would just push all of me inside her and keep it in. and i guess the position kind of was pushing my dick down. and i felt a little discomfort like when your penis pops but without popping sound from pushing it down. the lump i got is right above my balls as you can see (looks like a vein). been like this for 5 days. any idea? maybe hernia?
The photo does not show anything clearly - from what you describe it is most likely a Penile Lymphocele - these take their own time to heal.
If you can, totally back off, or take it real easy with sex and masturbation …
