In my experience... yes. Most of my exes never came when I gave them head and I thought I was bad at it, but my new boyfriend comes really damned quickly (even though normally he takes ages). So basically... yes.
If a guy ejaculates, does that mean it was good? or do you come whether it was good or not?
I would cum whether it was good or not, to be honest, so I don't think it necessarily needs to be good for him to cum. But if he says it was, why do you disbelieve him?
But also, to improve, talk to him. Ask him what makes him feel good. A blowjob should include the shaft, balls, frenulum, foreskin (if he has one), glans, urethra etc. Lots and lots of sensitive zones right there to make a 'good' blowjob 'great'!
I think that's why it was different with my new bf. Because stuff that my exes HATED he loves... everybody is different. Agree with Teagan on the asking him what feels good, remember... practice makes perfect
I don't know if there is such a thing as a 'bad' orgasm. They can however be good or great depending on how aroused the guy is, and how you reach that point is as much a part of the fun as the end result. The best idea is to ask him what he likes best!
It's the fruit that makes it fruity, it's the juice that makes it juicy, it's the funk that makes it funky, it's the junk that makes the junkie
Anything sexually related is essentially about communication. If he tells you it was good, that's very good news. The key now is to learn exactly what he likes so that he gets an even better blowjob next time. Just make sure you tell him to return the favour!
