So, my girlfriend and current partner is quite a bit smaller than me. I'm 6'3, 180 lbs, and 7 X 6. She's 5'4 and 110lbs. We've only had sex once, with it being my first time. We tried for a little while, and due to my height, I couldn't thrust while penetrating; the position was too awkward. My dick was bent down and then straightened halfway to even get in her, and my hips were too low to get any thrusting at all. Long story short: are there any positions you can recommend that won't put so much strain on me being on top? What are some of your experiences with smaller girls?
