Hi, I didnt know where else to go to without being embarressed.Anyways my prblm is im 17 years old and i masturbate regularly , and i think i get orgasms , but i never ejaculated. i dont know what im doing wrong.i do get precum however. basicly i masturbate when hard, till it reaches a point where i guess i have an orgasm, then im done. i tried to go further... just doesnt happen i get tired... the most iv done was 2times in a row. my precum comes in after like a minuit of my orgasm.also will this matter?.. im uncut. and i cant retract when hard whe im not .. i can no prblm. also one other thing, i had testicular cancer when i was 2 and had one of my testes removed.
