Should sex (for men) be avoided when you have sciatica problems? would sex aggravate the sciatica problem? when is it safe to have sex after sciatica?

Different position: Sciatica could be aggrevated by sex. But, a person could try different positions and may find some that do not cause it to get worse and are comfortable.

It depends: In general if any activity causes pain it should be avoided. If it does not hurt continue to be active. Sexual activity is personal. You can find a position or a way not to hurt.

Yes: However certain positions may make pain worse. typically herniated disks are worse with position in which your spine is flexed. Hard to say when you can be better. If you can flex and extend your spine without pain then intimate situations may be OK.
