my boyfriend can't wait till I am aroused, its dry and painful, but he continued, when I asked, he said that the longer he waits with an erection, the shorter the intercourse will be, like, he ejaculates fast, in 20 seconds. After a few months, and few more conversations later, he finally decided to wait till I say OK, he still pushes, but I made it clear. He still ejaculates in less than a minute, that too wearing 2 condoms at a time. He said, it was double the protection(for pregnancy), in case one bursts. Then he cleans and sleeps. Slowly he stopped having sex, when I took the initiative, he rejected. This is damaging the relationship badly, he is very egoistic, selfish and irresponsible, makes me feel like he has very little or no value for me.

What is your question? Do you want people to go knock some considerate and loving behavior into him?
We can't do that; you can't do that. I assume you have exhausted all efforts to talk about it.
Next step: leave.

He needs to see a doctor about possible issues with an erection. You need to demand foreplay and to be stimulated first or no sex.

We can't make him or you do what you want, you can say no till you are ready,

How old are you both.. Advice won't be the same if you are 20 than it would be if you are 50.

The advice above is good. Also, for him there are creams that will help dull the sensation and might help him last longer.

I am not clear on if he is selfish etc.. And he is a quick finisher, or if he is a quick finisher and that makes hi selfish... a little more info would help.

If he is a jerk... leave

He needs to see a doc. But you also need to put your foot down (politely of cours don't be a grouch) but say 'im sorry hon until I am ready we can't have sex'
So maybe try planning the nights you will have sex, and before you get HIM ready, get yourself ready. Use some lube, a vibrator, and get yourself nice and ready for him before he goes. It may increase his time as well.
Is he circ'd?

Two condoms? Not good!

The fact that he's wearing two condoms at the same time can have something to do with his quick performance.

Also, wearing two condoms isn't safer. In fact, it's the opposite.

How about he learns to have an orgasm and keep going? Or masturbate earlier in the day?

Either way, his d!ck shouldn't be anywhere NEAR you at this point unless he's getting YOU off first.

If he won't make the effort, then he's just a jerk and you should dump him.

And frankly--his story about the longer the erection the shorter the intercourse is about as believable as HAVING to have intercourse so he doesn't get blue balls. And frankly, if "longer" is 20 seconds, then who gives a damn how much SHORTER it could get? He needs to just deal with his erection, frankly, because that is not YOUR problem. YOUR problem is that you don't make him work to get you aroused.
