Yup, still cheating, sorry. Just because you are bi doesn't mean that it is any different. Saying that it should be an exception would be the same as saying that since your guy is attracted to women that he should be able to sleep with them when ever he wants.

It's definitely cheating unless you are in an open relationship where you both agree to see and be with other people and you both are ok with that. Otherwise you should just break up and find partners who are open to multiple partners.

yeah, that's called cheating.

That is still cheating sweetheart... any way you look at it.

Cheating. Find a more open-minded boyfriend if you want to go about things that way, and don't be upset if he wants to get with other girls.

If you are in a committed, monogamous relationship, that is CHEATING. Any break of that commitment involving another person is cheating, completely regardless of gender, gender identity, etc.

If it wasn't anything that you talked about before hand and had a good understanding about than it is cheating. Some guys might not mind it, but some guys would be mad as hell.

Sorry but I agree with your boyfriend. Why wouldn't it be cheating? Maybe you guys should talk more about what each of you expects in a relationship. If your ideas about what cheating is don't matchup and you can't come to a compromise that is acceptible to both of you, then it might be time to end the relationship.

Ditto to what everyone else has said.

Who or what sex is involved really isn't relevant. Any time there is a couple who have expectations of their partner being faithful and you add another party to that dynamic then you are in fact cheating. Hiding it and lying isn't going to be helpful to anyone. If there is any respect in the relationship with the boyfriend then you should let him know how you feel and what you expect. If it works then it works if not move on but don't lead him along. It's also kinda sad that there would be no respect for the additional party that you only see them as an object and not a shared experience. You should be honest with them as well.

It is cheating.

Because girls are just as much of a human being as guys are, and cheating is more about lying and doing intimate things without consulting one's partner than the act itself.

Unless you are in a polyamorous or open relationship, this is cheating.
