Nipple changes: Everyone's nipples stiffen. Sometimes because they are cold and sometimes caused by orgasms, but it differs from women to women. Men's nipples stiffen too so they are basically the same reasons. Hope this helped.

Smooth muscles: Stimuli cause smooth muscle contraction in the nipple skin making them firm and elevated.
