I am male, 20 years old. I could cum fast in about 2 minutes when i jerked off but i could go for a long time. Now it takes me about 30 minutes to an hour to cum for some reason and i can fuck forever. I can go for about an hour and half if i have to but usually it's about 50 minutes. I take forever to cum now. But it's good cuz it's not all over within 10 minutes lol. I kinda like having a long session in the sack.
