I guess this could be in either thread, pleasing him or her. But I put it here since I am a female and my man said it to me about pleasing him. I just wondered what the best compliment was that you have ever been given regarding sexual activity.
The other day after oral my man said to me 'I hope you enjoy it half as much as I do.' That made me feel good because I always wondered if he enjoyed it as much as I did! It's good to know we please each other 
So, what is your best compliment?
Well Vixen, I'd say that ANY affirmation by lovers towards each other - both in and out of bed - is ALWAYS a good thing! Probablythe BIGGEST issue that people struggle with in intimacy - and with relationships in general - is communications. From, "My god, that feels so incredible" to "Baby, watch your teeth" or "Yikes, your beard is kinda chafing me down there..can you use more tounge?" - we should NOT feel like we have to keep our mouths shut or thoughts to ourselves.
Communication is the key to better sex and a better relationship! It's all in the delivery!
I don't mean comments you blurt out in the heat of it Rawbob. I meant while you're all finished and enjoying the 'after' together. Ya know, like laying in bed snuggling or something and they gave you a gentle comment that just lights you up.
The best compliment I ever got was a long kiss and snuggling till we woke up the next morning. Sometimes words aren't the best course of action.
