First time i'm going to do sex with my wife once i married. I want to stay long time. May i use some tab or in?

We have no idea what you mean by "tab or in". Those words don't make sense in English the way you're using them.

If you want to maintain your erection during sex with your wife, masturbate several hours beforehand so that your arousal level is reduced.

1.your question is not very clear.

2.using medicines is digging your own grave, unless they are very much required.

3.there are some techniques. one of them is to stop in between & divert your mind for few seconds and again continue.

4.practice yoga &meditation.

NOTE; giving strokes for a longer time is not important. the most important things in sex are:

1. how much confidence you have given her about your love towards her.

2. how long & how best you do the presex play (this is a big subject). The greater the height you reach&jump, the greater the impact.

Note that the sensitive part in vagina is the first one and half inches depth only. so even with a small penis one can do successfully.

Do u mean tablets??? i think the best way to stay long is to have long foreplay with her !! soo let her reach orgasm first and then enter her !!! she will have more pleasure in that way !! When u feel like ejaculating inside her just stop before u *** and start stroking again when gain back ur erection !!

Go with natural yaar!!

artifical always comes with side effects

prolonged sex can gradually increases your time

Yes or you can come back for seconds.

avoid excitment by talking of ur own both
