OP

Yeah she can't take the pill or anything else hormonal because she's taking another med it won't work with so I always have to wrap it up.

I just can't think of a way to do this. I talked to her tonight and the whole time I was like "you need to tell her" and I just couldn't do it. It was really awkward too since she was talking about stuff she wants to try and the only way I felt was grossed out. I mean the only thing I can think of is just to come out with it and be like "yeah the last time we had sex on Saturday, I noticed you have some discharge that isn't normal and a smell, I don't think we should do anything until you get it checked out." And maybe offer to go with her so it doesn't look like I'm an ass that's disgusted with her body? How does that sound?
