I had an old girlfriend who told me she was bisexual but only for milfs, she wanted to indulge but she was always worried it would negatively affect things with us, which to her was more important.

She used to travel a bit with work and do small city breaks by herself though and we made an agreement that she could have any woman she wanted while she was out there.

Don't really know how much she got up to. I didn't demand that she keep me informed on everything, the purpose of it was to let her satisfy the urge, not enhance our own sex life.

She did tell me that she slept with an airbnb hostess once. Her profile on the app mentioned me so apparently she had to work really hard to convince her it was OK lol.
