So i have a few questions and at one point I'm going to sound like I'm bragging but i swear theres a point to it.. So I don't have performance issues when it comes to how well i do what i do. in fact every girl ive been with seems to be over the top wanting more from me ill get texts back over and over for booty calls... but thats not the issue i just want to be clear that i dont think its in my head... or at least not about performance... I can't cum... at all not from sex anyways if i masturbait i can cum, it takes a long time sometimes, and other times is 15-20m.. 95% of the time i dont cum at all from sex, ive only found that i can cum from sex if i go ATV'ing in the winter and the cold is hitting my crotch for a long time and then its like im a normal person.. when i'm having sex i need to be cold to maintain an erection.. and this to me is strange because everything i read tells me i should be the opposite but its not the case.. I've had this issue my whole life even the first time i had sex, doesnt matter who i have sex with still the same. I lasted 3 hours before without cumming and the girl needed to stop due to pain.. I've tried having slow sex. fast sex. ive tried alot of positions.. nothing. by the way I'm 25 years old now. and the first time i had sex was when i was 16.. And incase someone may think its psychological, i do have anxiety in general not about sex tho, actually i think its the one thing i feel comfortable with how i perform. I'm trying to cover every basis here to try and get an answer because i've talked to my doctors and their answer was i masturbait and/or have too much sex and I'm desensitized ... which i call BS on. i dont know if size matters in this case but incase it does im 7.5" and i dont know the girth size but its alot larger then most and i say that due to girls comments in the past... i know that breasts can be less sensitive due to larger size so maybe thats why... i am honestly out of answers.. my other thought was that maybe its because i dont really fall for these girls that i get with. its like i'm always settling maybe thats it... i dunno answers would be helpful. because id like to finish and not have blue balls directly after sex its kinda counter productive..... if you need anymore information that may help just ask i really have no secrets
