Help me I am confused ,Whos sexual satisfaction is more fullfilling your or hers


So I am a 46yr old married man with a 22yr girlfriend and would like to know if I am the only man that feels and thinks it is more fullfilling to satisfy your wife or girlfriend or (both at the same time) needs over and above my own and sometimes I dont even get mine and I don't care because I am completely and totally sexually satisfied.
Now the reason I am asking is I have a young girlfriend and she is always telling me that no other man or woman has ever given her an orgasm that made her knees and body shake and weak from such a powerful orgasm and never new they could ever be so wonderful
