Stay or LEAVE,which one?

I been in a relationship with my man for almost a year. My sex drive is soooooo much higher than his. Now I told him this, so it's not like this is something new to him. But dammit, I'm tired of initiating. He says it cause of his age(35), and he just can't keep up with me. He even takes stamina pills at times, just to get on my level, but after so much "talking", I'm drained. He's upset cause he says I make him feel less of a man,but truth be told, if I gotta masturbate when I obviously have a man,I need to be ******* him or someone else. I love him,but i refuse to continue this masturbating **** unless he willing to participate. What are ya'll takes on this ****? signing off, Ms.Sexually Pissed Off!
