tenting, ballooning during arousal!

Any women on here get too aroused during sex that there becomes less friction? It was never an issue in previous relationships. But my man now, he gets me so so aroused that I become absolutely soaking wet. Then my vagina muscles fully relax and there is a lot less friction. Which means he is working up some sweat trying to cum. Says he's never ever met a women like this and it's taken getting use to, but now that he has he abolutely loves it. But I'm still so paranoid about it. BecAuse eventually, I can't feel a thing, so I know he can't. And he has at times thinking he's funny kept me going about being wife, or that I could take two dicks. It hurts since I am so paranoid. But when I'm not aroused my vagina is tight. He will have trouble at first inserting his fingers. I've done my research and it's called tenting. Perfectly common and normal. Does this happen to anyone else? It just makes me feel I'm not pleasurable for him
