<s>[INST] ok this is embarrassing but I had sex for the first time with my girlfriend for the first time and 5 min. in I couldnt keep my erection. We tried again a couple days later and it happened again. now im worried that i wont be able to get an erection. could it have anything to do with my penis size im 4.5 in [/INST] HIT hank for asking to ChatDoctorerection and the size are nothing to do anything with each other, you have taken the side of your penis seriously that might be causing erection problem, you have to forget it size is not the matter in intercourse, again I am advising you that you have to forget it, stop paying attention, otherwise this will create more panic, hope this information helps you, take care and have nice time. </s>
