Define partner. If its some random I can go a long time, sometimes not cum at all. Long term, which can be a month lol as long as its looking long term...I can pop in 5 minutes or less.
Sex is all in the brain. With no connection it all comes down to getting yours, even if it means thinking of someone else or whatever it takes to blow. With someone you really like/love its more about how you interact together.
Best sex I had was with someone I was with 6 yrs. The majority of our sex was quickies. She had little kids when we first met so we had to when and where we could. Imagine how many truck drivers saw me getting road head or me fucking her with her hair brush while on a trip to see family.
Again, all in your brain. Everybody has a trigger .. or 10. Figure that out and sex gets a whole lot better.
110% facts
If your heads not into it your head won't be into it. Like with the right woman I can last as long as I need or I can legit just finish not even really moving just holding each other.
When I say get yours above I do mean with her desire why i say talk during it all. If you both want each other and really really have that connection trust me you will be fighting from finishing because your brain will want you to get her pregnant subconscious.
Some of the best sex ever has been just laying there on top or whatever face to face. When it's real it's good.
When it's good doesn't mean it's real.
Find what's real for you two and it will get better.
Like most women would rather you finish early time to time than never. If you never do they won't think you like them.
Imho if it takes a long time and trying to think of what I would do or what she may need/you subconscious.
I say slow down alot. If your gonna last that long don't just fuck. Start slow, take care of her in other ways first. Then "make love". I tbh don't lik3 using quotes because as cheesy as it sounds when you do, its way better. Find that emotional connection again. Like even establish that night and be like
"baby I'm gonna go down on you for a while then when I get done I'm going to come up and fuck you nice and slow and just take care of you for a little while I'm not worried about me I just want to feel us."
And do it. Legit spend 10minutes kissing everywhere around slowly before you even touch her p$$. Show her you care by caring about parts of her she didn't know mattered or don't think does. Go back up when your ready and just spend time loving her up close then you can consider the sex part. If she isn't begging for it she is holding back tears and gonna be real solemn and quiet and probably not talk much just give you nods and physical signs. Remember it's not about you at all and focus on her reactions. Learn to multi task fast with your hands and mouth while being slow at the hips. If she does not give you at any point the tingle like her hormones are effecting your current state. And if the next time you have sex things are not better. Then you don't have the mental connection you need to her.
