I have tried condoms and different positions and masturbation beforehand and sometimes they work but it's never a sure thing most of the time I still fail to last and when I do last it's still under like 5 minutes.

I can last quite a while during oral sex or when I'm receiving a handjob but when it comes to penetration my penis seems to go crazy sensitive and I can barely last like I enter and I'm instantly ready to finish I would really like help with this so advice is greatly appreciated.
