I have dermatitis on my fingers. I have had it four times and got rid of it four times but now I have got it back. I dont know whats making it comeback. I believe it is from masterbation. Im an 18 year old boy. And I have had jock itch also. And sometimes after I masterbate I get the pimple like lumps associated with dermatitis. Could it be the masterbation?
Thanks for asking in Chat Doctor forum I have not heard of allergy to semen causing dermatitis in any ones hand. Masturbation is harmless and cannot cause this. So, please give details regarding your profession, any chemical/cosmetic usage / usage of ornaments like ring for further suggestions. Jock itch is due to fungal infection which intern due to presence of moisture over there and not related to masturbation.  All the best. Will be waiting for your details.
