Is it ok to have sex with married woman who want child from you .?

If you do this, you'll feel used, and could have to face up to years of agonizing over this. Seriously if you have any self respect don't do this.

Personally I've few issues to being the third party in an affair, but not if you are just being used to an end.

Honestly, I truly think it depends on the situation. First off, you need to understand the full situation and know that you will probably not be a part of this child's life. You might be okay with that now, but you never know how you'll feel when the child is born. Also, think about how the child will feel if they find out that someone else is their father and that they have not known them. If her husband leaves her, she could sue you for child support, since legally, YOU are the father of the child. & you don't necessarily need to have sex with her if she's married.....you could just give her your sperm.

No, that's what sperm donation is for, you ejaculate into a syringe and then she pushes it inside her vagina (I don't mean a needle Syringe, she may poke her vaginal walls with it instead). Or ejaculate into something like a cup, and then suck it up wit the Syringe. Make sure everything you used is clean first.

It's best that she keeps her vagina elevated when she uses it, and stays in that position for a certain amount of time to give the semen time to flow down.

All it takes is ONE of the little bastards to hit the target THEY AIN'T TRYING HARD ENOUGH.

In any case no it's not OK, I'm getting sick thinking about it, could be your broken English too (not to be insulting, sorry if this isn't your first language).

If baby they want, you give sperm, they turkey baste baby

No it is NOT ok. She's cheating on her husband!!!
