You're not fully at fault, communication is key and relationships are a two way street. When you're not interested or don't want it. Let your partner clearly know that you're not interested and not to try again for whatever period you're not interested. A lot of people make a common miscommunication of saying things like "I'm not interested right now" which to some people means try again in a little while or they say things like "I'm kinda feeling it but not really" or any variation of that which shows partial disinterest so the partner tries again. You have to be clear, direct and thoughtful. Keep in mind that your decision impact both you and your partner, just as their decisions impact themselves and you. You don't want to become a dead bedroom or a frustrated relationship, at the same time you don't want to only be viewed as piece of meat or only a sex object. I'd recommend having a sit down and setting proper boundaries with your partner, find a compromise that makes both of you satisfied. Keep in mind that both partners are allowed to initiate and should, you want your partner to feel loved and not rejected. Healthy Boundaries, Good Communication, Mutual Respect, Honesty, Trust, &amp; Love. Figure out what works best for you guys and do it in your own way.
