So I love to use his cock but I desperately want to just give him the experience of me fucking HIM (riding him not pegging) while he does very little. However, it is really hard for me to sustain the thrusting part in cowgirl. Even though he says it feels great, I can't maintain it and end up feeling so weak and sad when I have to take a break. Is it normal for riding to be this exhausting? I start to feel so much pain and exhaustion in my thighs/calves/lower body muscles after like a few minutes that I physically can't keep going so he has to "carry the torch" from underneath me.

So is my technique wrong?? How do even weak guys fuck me while on top for 40 minutes at a time with seemingly no difficulty? For what it's worth I do exercise a lot and bike/jog frequently. I would be grateful for any tips either about form or how to make him feel more submissive while he is inside of me. I don't feel satisfied with my own skills yet as far as topping him during piv. If you know any exercises that help train dickriding muscles that'd be much appreciated as well.

I am going to see if he wants to try squatting/amazon position and if that is any easier for me. I also am not sure if he would want to do reverse cowgirl and if it'd be any easier but I much prefer to be facing him.

edit: i dont feel some pressure to do anything i just really love the feeling of fucking his cock on top and want to be able to do it more or find alternatives that feel as sexy and in control!
