I don’t know if you’ll be able to answer my

Patient: I don’t know if you’ll be able to answer my question or not but it’s about my boyfriend and pretty much our sex life. He’s 18 and he was able to last in bed for almost 4 hours with some of his ex girlfriends and his erection was pretty big but with me he can only last 2-5 minutes and his erection isn’t as big also every time he’s about to put a condom on his erection starts to go down, do you know the reason why because i feel like it’s my fault and i just want answers.

Doctor:
