Hi doctor I did a Hydrocele surgery 12 days ago when I can take a shower and when I can do Masturbation and drink alcohol I finished my medikal thx?

No fixed advice, but. For an average healthy 22- y-o man, an uneventful hydrocelectomy alone and its incision should heal well and should pose no additional risk to what you may plan to do as described. Nonetheless, without a direct look and awareness about how surgery was done and how your general health composure, it is hard to give 100% guaranty; one has to exercise commonsense for daily living; be conservative!
