I am a 25-year-old woman, and my boyfriend is 27. We’ve been living together for 3 years and have been together for 4 years. Our sex life has recently become non-existent, and we don’t know why. At first, we blamed it on the stress (end of the year), but now it’s been a month and a half.
We love each other and have a good relationship. I don’t know how to get things going again. I need advice please. Our relationship is great except for this one thing. I am getting very worried. (I’m sure he is not cheating.)

Schedule sex. I know you are already thinking “how unromantic!” BUT you get stuck in a rut in long relationships. Also make sure you kiss and touch everyday. If nothing more than a pat.
Have you guys thought about trying something different ? Doing the same things in the same place can make sex boring. Maybe make a trip to the sex store, go on a vacation for the weekend, dress super sexy, bar hop and take it back to the hotel room. It sounds like a change up is what you need.
