Okay first things first. I think you are thinking way to much into getting an erection. This can be a problem as the stress or nerves will get to you. If you are thinking things like that you have to stop.
You need to try and get comfy with each others bodies. Feel around and let her feel around you. Let her touch and get into it. The other thing is you may not be attrached to her sexually. But I think you are more worried about getting hard then you are not attracted to her. Relax. Breath and take in her body.
The other thing you may want to look into is getting in touch with your docotor and having them do a blood work to check out your testorone levels. This could also give you a slight issue with erections.
when she touches me she goes down my pants but i kind of moan but no sperm
i also see her nipples get hard but i stil cant get one
i use a condom so im not sure if that is the cause
yes we have. no not really, but i have seen her breasts. she doesnt really touch me.
No im not nervous. When i see her breasts i am not nervous
Has your girlfriend and you gotten intimate? Have you seen her naked? Does she touch you? Are you nervous when you are around her? Are you nervous when you see her naked?
