I have been with my girlfriend for about 5 1/2 years now and will be marrying her soon. The reason for the procrastination is because we're both trying to finish school first. Anyway, during our first 2-3 years of the relationship we had sex all the time probably couple times a week or more. Then it started to gradually die down. Now its once or twice every couple weeks, but we have moments. I also find myself looking at porn more often now. I pretty much masterbate more than we have sex. Sex was such a routine at the beginning and i'm wondering if it was wrong for us to have sex so much at the beginning. Is this something normal for couples to go through? I love this girl alot and I don't want it to become an issue when we get married. We've both agreed that its just something that happens when you've been together for a long time and its nothing we both complain about but I was just wondering if this is a normal thing?
