I had a FB who was younger than you and had that issue. Sometimes we would stop fucking for a few minutes so I could suck him hard again before resuming. The bright side is that it extended our session longer.
Don't you dare think that: that is not a truth that you need to face! There are guys in this forum and another similar forums who are much older than you are and write about wonderful, active sex lives. But I do believe you're right in that you need the right partner, as I do, where correct partner is defined as a person who is interested in giving you what you want and in the way you want it. That doesn't mean experimentation is verboten, but ultimately he or she is just happy to give it to you the way you like it, and is happy to take all the time that is necessary.
