(edit- yes I have made a terrible type)

So I pulled on a night out, half way through fucking her she goes 'you are really bad at this'.

I ask her to elaborate, she says ' you have no rhythm or beat, your like a dog humping away, don't you watch porn'

I genuinely do not know what I am doing wrong. No other girl has said anything like this.

If i know what the actual mistake i was making, then I would be able to improve.

In my defence the bed was pretty soft, and my hamstrings started to ache becuase of this.
