My partner is entirely silent during sex, until the very last moment when he climaxes. It makes it very difficult to judge how much he's enjoying it. I try to listen to his breathing but there's almost nothing to hear. It's very difficult to adapt your pace/learn what really works for them, when there are so few clues. I have to ask if I want to know how much he's enjoying it which is a bit off-putting. When I do ask he says 'What you're doing is perfect'. I guess I just expect more feedback. I can't help but make noises and I know he listens intently to me & plays me for a reaction. I'd love to do the same to him. Any ideas?
