Hi Cherry,

Sorry to hear about your problem. If I understand your problem correctly, your b/f is having difficulty with premature ejaculation, or at least not lasting long enough to satisfy you. When I was young, I had the same problem (now I have the opposite problem, it takes me so long to get off that my wife almost has to take oxygen after were through). Chances are your b/f is very sensitive to this performance problem and would not take suggestions very well.
One idea that worked for me is for you to try to incorporate his orgasm into your foreplay. For example, you could get him off early in the foreplay (either with a handjob, boob-job, or head; or you can be creative). This would also allow you to control his ejaculation, so that he wouldn't 'cum all over' you. After this, you should emphasize that this is not the end, and that he should do some 'work' on you. If he is anywhere as young as you, his little soldier should be back at attention in no time. And believe me, his second time around should last well long enough for you to get your's too (& maybe a few more).

BTW, the boobs sound great, would love to see them some time.
