Ada, a few of my mum friends mentioned their partners pakai Durex Extra Safe, mostly sebab thicker rubber dan less likely to break, yang important kan reliability, especially kalau you're not ready for another baby so soon! Tapi honestly setiap couple different, some prefer the feel of thinner ones even if slightly less "safe" feeling, so it's really personal preference lah. Better to try and see what works for you both, and of course consistent use je yang matters most.
