My girlfriend asked me if I had ever had sex with another girl before. She said she wanted to hear the truth from me, and she didn't mind. Should I tell the truth?

She asked all the questions. I suggest that if you really had sex in the past, don't tell her the truth. Just in case.

If she really didn't care, she wouldn't ask such a question. She said she didn't mind. The real idea is not that she doesn't mind, but that she is afraid that you won't tell her the truth, so she says she doesn't mind. But if you say it, it may be over.
