Thank you for asking what must be a hard question to ask. I will do my best to deal with it in the manner and respect it deserves.
First off – don’t feel weird. Every guy cums sometimes before they want to. That is normal. And like 1 out of 3 have premature ejaculation. Also, sometimes you may not cum when you want to as well, which can be equally frustrating, especially when you want to cum and she is trying her hardest and your anatomy is just not cooperating and you just have to call it quits. Women tend to blame themselves in these cases, which is totally not true. Or the other thing: losing your wood, which is super frustrating. All these things are just part of being a guy. Each of those have happened to me every so often since I was a teen. Cumming too fast if it’s been awhile since I felt that warm wet sensation, taking too long to cum or not at all if I am fucking a lot in one day and it’s one of the later sessions, or losing wood if it’s the 2nd or 3rd session in succession.
The difference is now it really doesn’t bug me when it happens, because I measure my sexual experience by how good it is for her.
That is what matters – how fucking wild and amazing was it for her?
How good it is for her is often a ton of foreplay. I spend a lot of time eating and fingering a woman long before I even pull my dick out. She naturally will want to please me with a blowjob. I highly suggest taking this opportunity to slap her hand and set the tone. Besides it’s hotter to get head when she just came and her pussy juice is all over your cock.
Be passionate. You don’t have to be super rough if you are not that type, but for God’s sake make her feel wanted. She will cum easier once she is in the right headspace and if you are eating her and fingering her to multiple orgasms before sex, she is not going to give a fuck if you cum faster than you wanted to, if she just had more orgasms than she can count. Break out a vibe or a plug and mindfuck her a little more. Have fun with her mind; it is the best sexual organ she has.
There are some things you can do, physically or in practice. I guess PE is really easy to correct too, so you may want to read up on it. Also, alcohol and diet are important, specifically for PE, so I just read. Plus, there are some techniques, namely two: Squeeze Technique (stop fucking and pinch the head of your dick and hold it) and the Stop-Start Method (self-explanatory). When I know I am hitting that “point of no return”, if I am not happy with how much she has cum or how intense it was for her, I might pull out and finger and eat her, which gives me some more gas. I guess the pinch thing would probably be a good idea but I just stroke and keep it hard.
Now I have never had a consistent issue with premature ejaculation, so I have never really needed to look deep into it, but the article below is good. I do like to stop fucking, and dive back in and eat her pussy and finger her just because it totally is the last thing she is expecting and it kind makes her lose her mind. It also sends a subtle message – ‘we are doing it my way, Kitten’. Submissive women want to be in that headspace so this is a step in the natural direction they want – for you to take control – in every little last way, even if it means pulling your cock out of her when she is about to cum and making her wait while you eat her pussy instead. And last, I heard also that it’s probably a good idea to jerk off every day, just to keep that dick active.
Hope that helps. Also this article seems to have a lot of answers for you.
