Unable to feel sensation in my penis.
So what happens I just completed a trek or a hike of 12 hrs( both uphill and downhill) about 10KM. That night we slept and nothing happen.
Next Morning me and my gf decided to get naughty and have a makeout session. Things becahme heated quickly and we decided to move further. For reference both of us are virgin and never had sex before.
Even when she was stroking me I was unable to feel sensation in my penis and was easily losing erection.
The main issue is lack of sensation that I felt - is it due to porn and mastarbation or I have some diesease.
Please help.
