I have been with my partner for about 7 months, we are both very horny people and have sex once every night/day we are together (about 5-6 times a week), however sex is becoming unfullfilling and samey. We always end up in the same position, and because he is on top he gets tired quickly and easily which therefore causes us to stop, which then leads to me going dry and him going flacid. I have noticed that after only a few moments his dick goes limp if we're swapping positions or we have stopped... I wish I knew how to turn him on more. How can we make it better? We have tried different positions, and I have tried different things like grabbing his balls and feeling his body, but it just seems more and more difficult to cum each time we have sex now, and we both know it. I love him, I don't want sex to get boring as it's such a huge part of our relationship and I want to spice things up between us, please help!!
