Its tricky because as ever its a balancing act. To not give credit where it is due is simply mean, to fawningly pour it out when it is not due is weak and simpy. There is also the probably bigger question of not what you say but what you do.

For example, you like her arse. You let her know. That is all good but there is a sliding scale here. Lets imagine that you see her bending over the sink in a light skirt. You decide its time for some spontaneous kitchen doggy style sex. She is well up for it and enjoys it as much as you do. You tell her how much you liked it and how much you liked the view. That is all good and she now knows that she can really make you happy like that and she can get your attention like that. There is no harm there -in fact its probably all really positive- but but if you start simping out and begging for a repeat not just picking the right time on the right day and making it happen then suddenly she has a hold over you and you can be led by your dick. If you are unlucky you have to do the washing up for a week just to get some doggy in the kitchen, if you are very unlucky you have to start taking her out first and buying her clothes that look great on her backside just to get what should be yours anyway. She won't even enjoy this as much as she did when it was spontaneous. She will have to start to decide if you are deserving enough and if there is that doubt in her mind, how can she enjoy it the same as if its what she wants to give a man of quality, wants to be appreciated by him and earn his praise? This is where you cross the line to the beta provider who has to earn enough stamps on his good boy chart to get some pretty dry pussy.

Its a hard line to walk and as relationships age you move more to the beta position anyway -its impossible to totally avoid- but if you base it on what is realistic praise and value? not from a fear based position of "what makes me look weak or thirsty?" it will be more likely to be OK. Women smell weakness pretty easily as they are repulsed by it so much. So its better to be over generous in plain good hearted compliment (not begging or trying to big her up to increase your good boy stamps) than mean from a fear position. Meanness was never known to make them wet either.

Give praise and credit where its due. Imagine a girl who didn't give that to you and consider how weak and insecure women can be. You might get a weak hold over an insecure woman for a spell of time like that but the joy in the relationship will die long before she leaves with stories of "emotional abuse". They really do value being told they have value but the moment you overvalue them and get a shortage mindset, then you become vulnerable to their manipulation. She has a good arse. There are better ones but you are satisfied with her, so long as she remains good company and willing in bed.

Sure!

I tell her how to dress when we go out.

I make her do sexual things that I'm craving. Like "send me a picture of what I'm going to have tonight". Or, "crawl on your hands and knees to me slowly. I want your mouth when you get here". I take the keys from her to drive her vehicle. I tell her where we are going and what we are doing. I tell her what to cook me or what we are going to have for dinner. I tell her "I'm going to the gym and your coming with me" I reward her with praise, time and attention" I revoke that if she doesn't comply.
