I want to date a lot of girls at the same time. What do you think about that?
Do you think it will be that easy?
It sounds quite simple. I'm already dating one girl.
It is great to have fun dating but you shouldn't do it when others don't know anything about it. That is cheating and could end up hurting the girls you date.
Dang, I'm not a cheater, I just like a few people.
If everyone consents to the open relationship and you are honest about it, it should be quite fine. But if they aren't okay with it, it would be best to not do such a thing and cheat.
