Is it the mans "say so" to start having kids or the womens?

So i want to have kids already but my boyfriend isnt ready.... Idk why.... we both go to college and have jobs... I told him i want a baby.. and he said No. so when he wants one , should i say no? to get him even madder cuz he said no to me first.? 😒 its kinda stupid to think about it.... I feel like its the women's decision to when to have kids NOT the guys.
