I'm sending you this message from the top of the Sierra Nevada mountains of California. My wife just experienced her best orgasm ever. We live by the beach, a very low altitude... so that made me wonder, although crazy, "Does altitude have any impact on sex?"

If it doesn't impact sex, it definately impacts the lube bottle as it came squirting out on it's own...

My boyfriend has trouble ejaculating, usually taking a long time. I was wondering if it could have to do with his constant masturbation during most of his young life. Could it be that the problem is me? Is there a possibility that we can improve the situation?

I was wondering if interval training could improve my ability to achieve multiple orgasms in one night. I had a friend who said he masturbated two times a day for three weeks, three times a day for another three weeks, four times a day for three weeks, and so on. He said this improved his stamina. I want to increase my output of semen as well. Any thoughts?

1) I have trouble getting an erection after ejaculating. I wait 10-20 minutes, but it doesn't get too hard. It sometimes annoys my girlfriend. Is there anything I can do besides waiting till the next day?

2) Are there methods through which men can regain their erection quickly following orgasm?

3) I'm not really sure how to ask this question, so I'll try my best. I know that there is a certain period of time in which a man has to "recharge" after he cums. And I was wondering what the time period is before a man is "fully loaded" again, if there is any at all. Sincerely,

Hi! I have a question about orgasms. I'm a female who has masturbated since her early teens and wonder if I've "overdone" it somewhat. I did it so frequently (sometimes every other day or so; sometimes I waited longer) that now that I'm in my early 20s, I find it harder to reach orgasm, and harder to have multiple orgasms (it used to come so easily to me). Have I "lost" that momentum? Can I regain it if, say, I stopped masturbating for several weeks or months?

Also, my partner stimulates me manually or with his tongue, and I haven't been able to "come" yet... is it because I've masturbated too much? Do women take longer to come? I think he gets bored doing it...

My wife and I had our first child last July. Until about 3 months ago, she was unable to reach orgasm at all. Of late, she has very small one's, but they don't seem to be getting much better. Prior to having the baby, she had strong, very quick (3-5 minutes) orgasms 90% of the time. I know the stress of being at work rather than home with the baby could play a part in this. Is this common and is there a way to mitigate the problem? 

1) What is the best way to learn how to prolong male orgasm when having intercourse? It seems that I might get thirty seconds of penetration before I blow my top. I'd like it if I could enjoy the situation and add to my partner's pleasure by helping her orgasm.

2) I just wrote asking about how I might prolong my orgasm so that my girlfriend might be able to reach hers. I've read through your archives extensively, so I've seen all the "orgasm is personal and shouldn't be concentrated on" so I've seen that and whatever. I just want one issue discussed: how to prolong MYSELF to please her. I'm looking for answers such as: exercises, workouts, diets, surgery (jk). Please help me please her.

I've noticed when I get highly sexually aroused, my fingers get numb, and so do my lips. Is this normal?
