Is it safe for your husband to suck your nipples during pregnancy?

This is hilariously embarrassing so I’m glad for the anonymous part, but google is saying it’s okay. However, I read a few posts where women were pumping while 25+ weeks pregnant to save milk for their babies (on a couple of different pregnancy facebook groups) and all the women came for them in their comments telling them to stop immediately because it could cause pre-term labor. Sexually, nipple play is one of our main go-to’s for me to get off, but if this is dangerous for pregnancy I gotta know 😅
