Recently I've managed to reach penile orgasm, without cumming.
It's pretty hard and requires a lot of control over your own body.
In general it includes stroking your glans (top side of it, that which you can see) with your hand with relaxed bottom muscles and keeping yourself from cumming having strong grip on your dick (perfect place is when you push hard with your fingers between your penile and ballsack).
The feeling is not the same usual orgasm but similar. You feel very horny, your heart races you can feel beeing on the edge and you feel strong impulses coming just from the surface of your glans. It also last much longer but you have to keep the feeling going yourself by continous stroking.
When you finally reach the point when the feeling starts to dissolve it means its over.
You also het the feeling of slight tiredness like after normal orgasm.
You can reapet it ofc.
