I don't understand why

Hello all!

Nearly every time my husband and I have sex

He doesn't cum.

He will get to a point where he is about to cum but then he will slow down or completely stop in order for him not to.

He gets up super easy... if I even just brush up against his penis he's up at attention.

Now I do know that he is paranoid about getting me pregnant but what's the point in having sex if he's going to stop himself from cumming

It's soooooo annoying!

He will literally almost cum, completely stop, and then pull out while saying “I'm not going to cum” and then start having an entire conversation about something else non sexual

Heeeeelllppp me please!
