impotence is usually referred to the inability to have an erection. assuming that you can achieve an erection you are not impotent. you may be infertile however since prostatic fluid is required to nurture sperm (from the testes) so i don't really know if this tiny amount of fluid contains sperm or not. the nature of this urethral fluid is really unclear so perhaps you can address this directly with your urologist.
does a prostatectomy make you impotent. i assume the answer is yes. confirmation is the reason for the question. i started dating a woman who is not on birth control and has not had her tubes tied. i had a prostatectomy 4 years ago. i was to be sure there will be no pregnancy. during self stimulation at times i have seen a drop or so of fluid that looks like semen.
