i saw blood on my hand what does it mean?

Hi,
Welcome to ehealthforum,
Vaginal bleeding during or after intercourse/masturbation that you describe is not normal and could suggest chances of infections, internal injury/trauma, cervical erosion or dysplastic changes, uterine fibroids, endometrial polyps, endometritis, ovarian cysts, hormonal derangements affecting the bleeding pattern, anemia etc. It is difficult to comment on the cause for the abnormal vaginal bleeding that you describe without examining you. The exact cause can only be made out after careful evaluation. Visit your doctor/gynecologist at the earliest for thorough examination and further evaluation to look for the underlying cause for the bleeding during or after intercourse that you describe. Treatment as indicated (based on examination findings and investigations results) would be started to help you in controlling your symptoms. Consider being in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet. If infective cause is detected, get your partner also treated simultaneously to prevent chances of re-infection. Avoid sweat accumulation in the area. Keep the area clean and dry. Avoid vaginal douching, or use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid use of tight fitting clothes.
Take care.
