why is it that my husband can have multiple orgasms by him self if i watch him and when we make love he can only do it once please help me understand
Sounds like he's a talented one and believe me there's not many out there, I believe it's all about control and experience, kinda like mind over matter. Have fun with it and if you're curious, go on some sex web sites that can help you with this.
Google it, good luck!
