Im 26. Male. Overall good health and size. Only rx is generic wellbutrin started 4 months ago. Over the last 4 weeks i have noticed about once or twice per week, after a bowel movement i expell semen instead of urine. No pain or discomfort. No unusual odor or color. Normal amount compared to sexual activity. There is no stimulation or. arousal before, during, or after. My sex drive has dramatically decreased over the past 2 months as well. Although this isnt a concern, it may be helpful in determining the cause of the ejaculate coming out.
