TMI....

So im 26 and have 1 child. I think im addicted to sex... But i dont cum like i want to. Me and my friend did have sexbutit don't last long. And i can occasionally masturbate and getoff in 5 minutes or less. When i masturbate, its clitoral stimulation only... And i enjoy the feeling building up to it and feeling the pulsing and surges of my muscles but i don't feel satisfied afterwards... I feel myself and i came but no satisfaction what so ever... Is something wrong with me????
