How do you last longer in bed?

Hey guys.

So yesterday I sexted with this girl (without touching myself) and it was amazing. We were both really into and I felt a strong connection to her. I absolutely do not regret it, in fact it's quite the opposite, and I want to meet her in real life. We would very likely have sex, I can feel it.

I had a 13 day streak and reset yesterday at night, just MO, and it actually wasn't a bad feeling when I did it (feeling and orgasm was amazing). Only problem was: I couldn't last long. I know that the sexting was triggering and such and such, but that's not what I want to discuss.

See the thing is with sex, when I have a streak (even a short one, say 4 days), I'm very turned on, masculine with a deep voice and it usually leads to awesome sex (in terms of foreplay, talking and everything) when I have it. But when it then comes to actual stimulation, I just come very quickly and it is so annoying. I know some techniques to apply to hold back a little: Slow deep breathing, focusing on the sensation and tightening up your jaw (that's a weird one but it works). And they do help a little, however just for short. When I continue stroking I start to lose control. When orgasm comes closer I need to stop and at this point even a small touch can get me off and I have to be super careful. Then when I do come because of that, it's the most frustrating orgasm you can have. It's really a gamble if I can stop early enough. And when I did, I have to wait a while because every little stroking leads me to this point again really quick.

This is only the case when I have a streak. Any shorter (like, up to 2 days) and I can control it pretty good if I'm not to wild. Beyond that, i start to lose control and I can't pleasure her with penetration for too long (and I don't like it either). I know there are other ways to do that but that's not what I'm after.

I actually have pretty weird thoughts because of that, like 'you need the perfect number of days abstinent to have good sex' and stuff. I'd like to feel confident no matter where I am in my streak.

So the advice I'm seeking from you guys is: How do you last longer and remain in control of when you bust a nut despite longer streaks?
