Hi ! I just have a problem and I wanted to know if some of you have ever experienced the same things

Here’s my issue : When i am masturbating i orgasm every time and without any problem, it’s not taking long and i mean it’s very good

But when I am with someone else i can’t and i don’t know why :((

I had 3 boyfriends in my life and none of them made me cum.. i have already tried masturbating while we have sex like i do it when i am alone and i just does not come :(( it makes me really sad

And it even does not feel the same when i am masturbating alone and when i do it with someone, i just don’t understand
