I was reading on the askmen site about bad things about jerking off. it caught my eye as I jerk off 2-4 times per day, 365 days a year, for the past 7 or 8 years (im 22). this is a quote from the site "we each know the secrets to getting ourselves off. Masturbating can sometimes create an individual orgasm effect where we train our bodies to respond to our own familiar touch and have a reduced response to other peoples touch, resulting in a tougher time reaching climax with others. A lot of guys can relate to this." the bold part is what scares me. when fucking my girlfriend it just doesnt feel as good as jerking off. not as tight (shes not a loose slut) and im not that small. 4.5-5 inch girth. maybe its just because she is so damn wet down there? when I start to fuck her very hard and very fast, I hardly feel anything in my dick. Its hard to tell if im inside of her or not, and especially hard to tell if im still rock hard, or just half hard. I can definitely tell when im about to cum though. I am very new to sex, I was a virgin when I met her 3 months ago and she doesnt know that. and not trying to brag, but I think I did very good for a virgin!!! (im good at improvising things!!) so I was just wondering if there is anyone here that can relate to one, or more of my problems/questions that I have posted here. thank you!
