What can this be

When making out with a girl, it feels good and o have precum, but I cannot get an erection. What can this be? Is blue chew a good idea to take for next time? When I’m home thinking about the encounters I have no problem getting an erection but it’s in the actual moment that’s a problem

That sounds like what I’ve had: performance anxiety. When I would watch porn more regularly there’s no problem but with someone else I would get nervous, my body goes into fight or flight and I couldn’t relax enough to stay hard. Try some breathing exercises maybe meditation. Whatever works for you

Sounds like PED.
Try having a deep conversation with her. Tell her you’re nervous. Be vulnerable. It can be very useful. Make sure she knows it’s not her. It’s in your head. Maybe in the next conversation suggest something she could do to help: be encouraging but not expecting…, talk dirty, allow a night all for her.
My trick for myself is to get her to finish 2-3 times before my boxers come off. That takes the pressure off me and my dick. If I don’t get it up- she’s already satisfied… somewhat. My girl doesn’t finish with D alone so I need a finger or toy to help her finish anyway…
If I do lose it, I try not to panic, and just rub it on her. She loves it. Had cum from just that. Seeing and hearing her reaction usually get me going again!

Good luck man!!:four_leaf_clover:
