Having Sex with my partner without Tadalafil

So I’ve opened up to my partner recently about being reliant on tadalafil the blue chew one, and we tried without and for the most part it went well and felt great. She mentioned how sex felt less robotic and that she could tell it felt better for me. But I feel like I finish much faster and it takes much longer to go another round if we go again. And I always alittle worried that I’d let her down and not be able to keep it up. Any suggestions?
