how would it not be cheating is a lesbian/gay relationship less real than a straight one?
I find this question a bit insulting.
also i am a lesbian so of course i dont want my partner with other women!
if your partner is not ok with it, it's cheating. But my boyfriend is ok with me wanting to be with other girls, because if i get it out of my system now, or experiment to see if i like it now then when we get married he doesn't have to worry so much. its better now than during marriage
sex is sex so be open and ask if you can have it with another person so long as they have medical documentation that says they are clean. Else I will be luaghing when you are at court losing in a divorce proceding because there is medical documentation that you where an idoit and cheated. STD Sexing The Diseased.
I agree with what seems to be the majority. If permission isn't given it's cheating. Even if your SO thinks it's hot, it's still technically cheating. You should use your own moral compass to know if you should do something, not whether or not it'll hurt someone.
