Yes! And, for good measure, YES.You may not have meant it that way but that's the only way it can be taken.
This guy doesn't need to be the one to make her cum with his penis. If he can't accept that A WHOLE LOT of women just aren't gonna cum easily with peen in pussy sex and that his partner may be one, that's not my problem. And I don't feel bad for someone who lets their ego get in the way of giving a fuck about ACTUALLY pleasing their partner.
Nothing against you personally. Or even the OP. I'm just making a very obvious observation. If dudes care more about being the most amazing lay ever than actually wanting happiness for their partner, even if it means they aren't the ones causing the pleasure with their dangling bits, then I care not about their insecurities. They have other qualities they need to focus on.
Guys get so fucking bent out of shape over the idea that if they can't make their woman cum, then THEY feel like a male-failure. Like the end-all goal of being a man is to be the only thing on earth that can make a woman cum. Sometimes my wife doesn't really get off when I give her oral, sometimes it takes seconds, sometimes after minutes its not going to happen. Then I try something different, and it works, or even that doesn't work. Then I ask if she wants to use her fav vibrators or auto toys. She cums her brains out while I'm with her, being intimate with her. And it makes me very happy. If she's cumming, I'm ecstatic. Do I love to make her cum? Of course! But, do I just love when she cums, regardless? Of course x100!!
Its the guys that place their manhood on the "gift" of being some magic entity that is solely responsible for their woman's pleasure that bothers me about men. As if she taking the power into her own hands, or even if he takes the sex toy in his own hand, and she cums from that, its a complete and utter strike against his manhood, then let me tell you, man, you don't have a whole lot of manhood to be ashamed about. Its just yet another way for guys to pawn off their inadequacies and bruised masculinity onto women. That's how I read it and always have.
