:confused: I am 27 and have had the same partner for 8 years. We have 2 kids 7 and 4 in age and about 2 years ago I started to bleed a little durning sex. I asked me gyob and she thought it might be an infection . After ruleing out that I am still unsure what it could be . I seem only to bleed when I am aroused or in the in top position , other than that I don't. I need to know it if it seriouse and how to fix it .please help.

It is possible that your partner's penis is hitting your cervix. The friction of intercourse could be just abrasive enough to break the skin and cause the light bleeding. One thing that makes me think this is your statement that it happens when you're on top. This may be resulting in deeper penetration at an angle hitting the cervix.
Also, after having 2 children, you could be experiencing some mild prolapse where the cervix drops down as you age. Thus, it didn't happen the first six years but has been in the last 2 years.
I would suggest you and your partner try some different positions for the next several times with less penetration. If there's no bleeding, then the odds are the problem was from bumping the cervix.
Hope this helps.
