I was on combo of Cialis and Flomax. Flomax was preventing ejaculation and had orgasms I am on only cialis now. When masturbating, I have blood in my semen. What I can take to stop. I see my primary n urologist every 6 months have elevated PSA level and enlarged prostate. Per MRI and biopsy no cancer or lesions. Want to ejaculate normally. What can I do?
