Differentiating between normal and abnormal vaginal bleeding can be a complex issue, especially for women who are sexually active and experiencing changes in their menstrual cycle or bleeding patterns. Based on your description, it seems you are experiencing light bleeding after sexual intercourse, which raises concerns about whether this is a normal occurrence or indicative of an underlying issue.


Understanding Normal vs. Abnormal Bleeding
Normal Vaginal Bleeding:
1. Menstrual Bleeding: This typically occurs every 21 to 35 days and lasts between 2 to 7 days. The blood can vary in color from bright red to dark brown and may include clots. The flow can also vary, starting light, becoming heavier, and then tapering off.

2. Ovulation Bleeding: Some women experience light spotting around the time of ovulation, which can occur about 10 to 14 days before the next expected period. This is usually light and short-lived.

3. Implantation Bleeding: If you are trying to conceive, light spotting may occur when a fertilized egg attaches to the uterine lining, typically around the time your period is due.

Abnormal Vaginal Bleeding:
1. Postcoital Bleeding: This refers to bleeding that occurs after sexual intercourse. It can be caused by various factors, including cervical or vaginal irritation, infections, or more serious conditions like cervical polyps or cancer.

2. Irregular Menstrual Cycles: If your periods become significantly irregular or if you experience bleeding between periods, this may indicate hormonal imbalances or other medical conditions.

3. Heavy Bleeding: Soaking through a pad or tampon every hour for several hours is considered heavy bleeding and should be evaluated by a healthcare provider.


Your Situation
From your description, the light pink bleeding after intercourse, especially if it is accompanied by discomfort during penetration, could indeed be due to friction or irritation of the vaginal walls. This is particularly plausible if you are not fully aroused or adequately lubricated, as insufficient lubrication can lead to micro-tears in the vaginal tissue, resulting in light bleeding.
However, it is essential to consider other factors:
- Infections: Even if you have been using condoms, infections can still occur. Conditions like bacterial vaginosis or yeast infections can cause irritation and bleeding.

- Cervical Issues: Conditions such as cervical ectropion (where cells from the inside of the cervical canal are present on the outside of the cervix) can lead to bleeding after intercourse.

- Hormonal Imbalances: Fluctuations in hormone levels can also cause unexpected bleeding.


Recommendations
1. Monitor Symptoms: Keep track of when the bleeding occurs, its color, and any associated symptoms (like pain or unusual discharge). This information can be helpful for your healthcare provider.

2. Use Lubrication: If discomfort during intercourse is a recurring issue, consider using a water-based lubricant to reduce friction.

3. Consult a Healthcare Provider: If the bleeding continues, becomes heavier, or is accompanied by other symptoms (like pain, unusual discharge, or changes in your menstrual cycle), it is crucial to consult a healthcare provider. They may perform a pelvic exam, Pap smear, or ultrasound to rule out any underlying conditions.

4. Open Communication: Discuss any concerns with your partner to ensure both of you are comfortable during sexual activity. Sometimes, simply adjusting positions or ensuring adequate foreplay can alleviate discomfort.

In conclusion, while light bleeding after intercourse can sometimes be normal, it is essential to remain vigilant and consult a healthcare professional if you have any concerns. They can provide a thorough evaluation and peace of mind regarding your reproductive health.
