Hey there.  I dont know if this is a problem or not but I wasnt sure so I thought it would be worth asking.  When I do a poo after having recently masturbated I occasionally ejaculate slightly if I have to strain to produce my excrement.  I do not suffer from this any other time, it only occurs after I have recently masturbated, and even then it doesnt happen all the time.Im 19, 6ft tall and have no relevant medical history.
Hello, Sometimes because of over excitement, it can happen. For the only occasional episode, you may need not worry about that. But if it occurs frequently than further evaluation should be done.  Hope I have answered your query. Let me know if I can assist you further.
