I am having problems cumming when with a girl and when I have a condom on I barley feel anything. I was circumcised at a young age so I won’t have the same level of sensitivity as a uncircumcised man. On my own I have no problems what so ever. Of course my girlfriend loves it because we can go on for ages and she will be brought to orgasm several times but she gets insecure and blames herself when I end up finishing sex without cumming. Is there anyway to increase sensitivity or make you cum faster?
