hi! me and my bf have been together for 8 months, we have been sexually active for 6 months and I have never made him finish. Not once. the only time he did finish is when he jerked himself off and then i put my mouth on his tip and when he did finish he was watching porn in front of me while i was just laying there braless and pantsless. i feel shitty about it. i have talked to him about it and he say he just has high stamina, but even when i ride him, or we fuck, or i give him head he still never finishes. He was the one that took my virginity but he had multiple bodies before me. i just feel like im not good enough for him, Any advice or tips?

edit: i forgot to add when i talked to him about it he also said something about how he thought it would be different and when i asked him to explain he was like i dont know i just thought it would go differently.
