Help!!

So my kinda boyfriend recently told me he’s never finished from a handjob or blowjob ever (even with other girls), he didn’t for a bit (but I wasn’t doing it for long) but the last time I did it he came after maybe 2-3 minutes.

He said it felt different, like not much of a relief to when he does it, but he said he definitely came cause obviously there was cum and he also said he’s not hard anymore.

Do u think it wasn’t much of a relief cause I didn’t like tease him? Maybe making him harder? Or maybe doing it for longer? No clue

Also, he said he doesn’t like feel post nut clarity or whatever, but it was kinda weird for a bit after but then went right back to normal. By weird I mean he just didn’t know how to explain himself about it feeling different.

Any advice??
