I guess my problem differs. I have an insatiably high libido and love sucking my boyfriend and getting fucked by him. He's naturally 9 inches and very thick, but takes his time entering and fucking me. However, I see him twice a month because he lives in Boston and I reside in DC. When we fuck, it's once while i"m there for a week. I'm horny all the time and initiate sucking him EVERYWHERE. From the kitchen, living room, all night long, and he keeps pushing me away saying, i'm not in the mood. When I suck him, he's in love with my throat. He says he loves the head and though i've never received any problems, i've asked, "what's going on, am i not pleasing you." each time he says, "it's me and you're insatiable." Now, I've stopped sucking him as much, but hunger of it more often. When I do suck him, I allow him to suck my throat like he's fucking my ass, deep and hard in any position, but he says, i wear him out. I'm not sure what to do cause i'm a horn dog...plus i'm 25 and he's 42. does a dude's libido decrease?
