OK, so this is going to be long.

- On your not being around much longer - even though sex and orgasms are beneficial to health, they are not overwhelmingly beneficial to longevity, and there exist and have existed numerous octogenarians amongst the ranks of nuns and monks, proving that you very well might be around for much longer even if you remain a virgin, although, of course, I hope that you would soon have your sexual debut

- if you have extra money, talking to a sex therapist might be a good idea

- normal women enjoy being passionately wanted, even in the day of vibrators. A woman can get positive physical experiences from a vibrator (I do not have vibrators yet, but women report positive experiences from vibrators all the time). A woman cannot get expressions of passion from a vibrator. So when you say that you fear "Underperforming= not being able to satisfy my partner", you are talking about some tricks or moves, right? (And yes, perhaps a sex therapist or a skilled prostitute in Canada can teach you those). But tricks or moves are not so important in the age of vibrators - humans look for sexual partners in the age of vibrators because they want a long range of things that vibrators cannot deliver, and you have all those things - you get turned on by women so you would be able to express your passion and desire in bed, you appear to be quite promising in being able to appreciate the more refined and subtle parts of human sexuality, and, in non-refined non-subtle terms, you are very hungry. All of those are things that a woman cannot get from technological advances in the field of sex. So you should realize that your sexual humanity is a valuable thing!

Regarding being 31:

A close male friend of mine was a virgin until his 40th birthday. He eventually went on to marry a woman 20 years younger than he is.

So, I was the person to give him the 40th birthday present because it was fun to me - it is unusual for a man to remain a virgin for so long, so, I thought, I would, for one, give him the birthday present (his birthday is in the beginning of August, so I was home on vacation from grad school, and generously inclined), and, for another, do something that women normally do not get to do.

In hindsight, he claims that it was not the kindest thing to do on my part, because he became hopeful that I would finally marry him after years of his unrequited love for me, and it hurt him when I simply said "bye" at the end of the vacation and flew back to continue in my degree program. So now he claims that I was cruel. I still think that I did the right thing, and he reports positive sexual encounters with a number of women, from time to time, until he met this woman, 20 years younger than he is, in an advanced degree program they were doing together, and she married him. They do not have children. At some point she wanted to have lots of children, but then stopped even mentioning it.

So this long story is here for a reason:

1) He was able to marry a childless, burden-less woman.
A) she is reasonably pretty, face-wise, and has a fine petite figure,
B) she was married earlier in the days of her youth, had other options in terms of male attention so she was not in any way desperate marrying him,
C) she is self-supporting financially through her small business so she did not marry him to get a stream of income from him,
D) she has several advanced degrees and the small business that does not utilize them is her choice - she could do other things with her life, things that require a lot of education, and
E) she is 20 years younger.

In this society, many people would consider it a "success" for a man to find a wife so much younger without money tarnishing the picture... right? So his delayed sexual debut did not harm him.

2) When we had those love making sessions in August on and right after his birthday, he was wonderfully passionate and did not have a single performance problem!! He was very funny asking questions such as: "So is this how a woman has orgasms?", but he was not in any way defective or "underperforming". He was just fine.

The one big thing that he did not get is children, and now that he is 50++ and the wife is 30++, it might be that he will always lack children in his life. But other than that, he is successful and OK.

I hope you will do better than he did, not stay a virgin until 40, and, if you want to, do have children in your life.

You should also read this forum in depth, and you will see reports from people, both men and women, with complaints that their partners do not want sex. And you do! You do want sex, you are able to get aroused, you are not on otherwise-life-saving medications that would kill your libido, you did not suffer from abuse, and you have the capacity to feel and express passion. So you are basically fine and just need a woman to appreciate all of those gifts.
