Can a relationship with conflicting political views survie?

Unfortunetly, you can't change his views on sex before marrige since it's got to do with his religion. You'll have to talk to him about it, trying to avoid any unwanted arguments, and you'll just have to understand that loads of people have different views on things, and some depend on their religion. You could possibly avoid the topic, but since you want to be with him you've got to sort things out ^_^

I think you should talk to him about it. Really try to understand his point of view, and then really try to talk him through how you feel as well. I think it's a little odd how he's bisexual, but is straight and narrow about sex. I know that might sound kind of horrible, but for someone who is so open and comfortable with his sexuality, it just seems odd to me, but that's probably because I'm not religious and I personally think it's smart to make sure you are 100% compatible before marriage, emotionally and physically. I think you two have a lot in common already, so if you communicate a lot and meet one another in the middle I think the relationship can work out. But if it doesn't work out, it's no big deal and there are plenty of fish in the sea, as they say.

Sit down and have the tough talk. Ask the questions you are afraid of asking, because those are the answers you need the most.
