maybe just don't get so excited. I naturally take a long time, but over-stimulation will speed things up. I was taught control as a teen by a woman who knew what she was doing... she straddled me cowgirl style and every time I was about to cum she would stop & just sit there until it passed, then start riding me again. Paying attention to things - both me and the woman - is the key. I can last for hours if I want to, but sometimes I have no choice. On the downside, a quickie for me is like 20-minutes, I've learned how to "fake it'..
