<human>: Can you summarize the given text in a few sentences?

Ive been with my boyfriend for a long time, and we're geographically separate (I'm in the US and he's Danish). We intend to get married in a few years and I intend of moving to Denmark.

He's bi-sexual and he's never been with a man or been with a lot of women. I flat out told him I don't feel ok with him sleeping with women but feel sort of ok with him sleeping with men, as long as he gets thoroughly tested before sleeping with me again. I also said not to tell me, sleep with the same person twice, or sleep with someone who has feelings for you because I feel like that would cause a lot of problems.

I'm not sure if this is a good idea or some weird logic and I'm paranoid hes going to just continue this activity when we live together. I'm not sure if this is good for our relationship and will pull us together or break us apart. I'm putting a lot of trust in him, but he seems more into sex with other people than I am, since to him it's more physical but he's emotionally attached to me.

P.s He didn't bring this up, it just came up in a conversation one day when I saw an article about cheating.
<bot>: Letting boyfriend sleep with a man at least once to know what it's like so he doesn't cheat on me in our marriage from some mid life crisis or aching curiosity. Not sure if good idea.
