How important is sex in a relationship percentage wise?

I'm asking because my GF and I had an argument if sex is important in a relationship. I'm asking in a relationship over 3 years minimum because I know the first couple of years its usually about sex.|||50%. Its the best way to be completely connected to each other (if you do it right).|||I just hit the three year mark. I think its important. Were both still horny lol just not as often obviously. I dont want to say percentage wise. I just think its important because both need and want sex and if we dont get it wed grow apart and get grumpy at each other. we still have sex like 2-3 times a week.|||I am going 2 say 55%|||I think it depends on the induviduals really. I think I'd say about 50%, it's a big thing, but it's not the only thing.|||95%|||93.7%|||51% )|||Depends on how Comfortable both you and your girlfriend feel. If you feel that sex is SO important , then I would probably say about 80% important. If you feel that you need to develop more knowledge about her and understand her feelings as a mature person, then I would say sex is about 40% important. It all fluctuates based on your level of comfortableness with your girlfriend and how comfortable she is with you.
