This topic is about a man who is two weeks post-surgery after having his rectum removed. He is experiencing some changes in his sexual function and is seeking advice and insights from others who might have gone through similar experiences. Here are some key points and advice shared by others:

- The symptoms described, such as the sharp bladder pain and the trace of brownish fluid, are likely signs of retrograde ejaculation. This is when semen enters the bladder instead of exiting through the penis. It's a known condition, and there are resources available to understand it better.

- It's important to remember that healing after such a surgery takes time. Two weeks is quite early in the recovery process. While some stitches may dissolve around day 10, nerves and scar tissue can take much longer to heal, sometimes up to two years. Improvements in sexual function can continue well beyond the typical six-week recovery period.

- Many people have shared that they experienced similar issues early on, such as "dry" or retrograde ejaculations, but saw improvements over time. Erections often return, although they might be less firm or accompanied by a reduced libido. Younger individuals tend to have a better chance of a near-normal recovery.

- Medications for erectile dysfunction, like Cialis, might be helpful. It's best to consult a doctor for a prescription and start with the lowest effective dose.

- If there have been additional treatments like radiation, these can also affect ejaculation pathways, and outcomes can vary from person to person.

- Retrograde ejaculation can impact fertility, but there are options available, such as medications and assisted reproductive techniques. It's advisable to discuss these with a urologist if having children is a goal.

- The presence of a small amount of brown fluid shortly after surgery might be residual blood. However, if pain or bleeding persists or worsens, it's important to seek medical advice.

- Patience and open communication are crucial. Anxiety is normal, but it's important not to jump to conclusions too quickly. Having a supportive partner, seeking counseling, and exploring alternative sexual techniques can help maintain a fulfilling sex life. Remember, sexual fulfillment involves more than just physical function; creativity and mutual exploration can be very rewarding.
