So i love my girlfriend. we have really really good sex but like recently like the past new months when she fingers me I have bled. Not a lot but like a good amount during and after. it's definitely not spotting or my period because I am on birth control to regulate that. It doesn't hurt when she does it and it is no where near my period. I am just so confused I have had sex with men in the past and this has never happened. I just am super confused. Advice or ideas ? What's going on ?
