Why is it

[Omega]

When I masturbate in any position it takes around 20-30 minutes

But when I have sex it only takes bout 5-6 Minutes?

How can I slow it down? And me and my gf were going very slow also...

Sex is different. With masturbation you have more control but with sex you have a lot less control over how long you can last. As you get more experienced, you'll be able to become more comfortable and be able to last longer. It just comes with experience and practice.

Ant is right, but I'll add that your body tends to get used to masturbation, which may cause longer times to 'get off' or may prevent you from experiencing an orgasm (which is less enjoyable). Sex is different, as Ant pointed out. It does come with experience and a lot of practice. It's no lie that most men would like to last longer in bed and want to slow down. There are many techniques that you can practice by yourself or with your girlfriend that can make your sexual experience more enjoyable. I don't know if we are allowed to give direction to those techniques, so I'll stop while I'm ahead :D

Yes. As you get more experienced you last longer. Also sex is so much more pleasurable that its gonna take so much of a shorter time. I think that you should take a visit to JW.com and find ways to maybe simulate a vagina and practice a little. Im also gonna stop while im ahead so yeah. Just use your imagination!

Something else to try is implement foreplay, rather that going straight in for the homerun ;)

It mostly has to do with arousal. Since you're alone when masturbating, it may take quite awhile to ejaculate. But when having sex, you have your girlfriend, who is not to mention naked. Something that is a fantasy, and that is right in front of you are two different things. But this might not seem much like advice since you're 18 and I'm only 15, who has not experienced sex, or even masturbation with his girlfriend, or lack there of...

Anyway! Basically, the level of arousal all depends on what you see. Like i said, something imagined, and something real and has form are two, very different things...

I'm also 15. But I found a good way to make me last longer! The climax control condoms!

Couldnt have said it better myself. You have the fantasy of sex in your head when you are masturbating but when it comes to reality its a much stronger feeling.
