i've been sleeping with a girl for almost a month but not engaging in sexual activities. today she gave me a blowjob and it took me really long and finally i had to masturbate to finish because we were running out of time... in the past with girls i've had serious trouble reaching orgasm and ejaculating. i dont want this to be an issue. when i masturbate i have to go really hard and fast. i'm going to stop masturbating. i'm not circumcised if that makes a difference but that's not really an issue here.
what can help me to orgasm with her more easily?
