Male - had stomach liposuction - having extreme difficulty reaching orgasm during intercourse.

I have had patients who have had sex the day of surgery, despite me recommending against it!  If you are unable to orgasm, you should speak to your physician, this is likely not related to the surgery.  Best, Dr. Emer.

You didn't state when your operation was performed. After any operation, including liposuction, there can be some sexual dysfunction as the body adjusts physiologically. This should correct itself within a few weeks.

Liposuction by itself will not have an effect upon your sexual performance. However, recent surgery is stress and any stress can affect performance. Also, pain medication may also make it more difficult to succeed. Otherwise, I would recommend that you consult with an urologist.
