What can i expect from an enlarge prostate, sexually and mentally?

Usually not much: BPH (benign enlargement of the prostate) has no direct effects on either sexuality or mental health. Some medications for BPH can alter sexual functioning. Finasteride & dutasteride/avodart alter testosterone metabolism, which can reduce libido or erectile function, while Alpha blockers such as tamsulosin/flomax can cause retrograde ejaculation by relaxing the bladder outlet.
