I’ve been having trouble keeping an erection standing up specifically when girls ask me to do doggy I don’t know if it’s a health related issue I never have this problem in any other position that doesn’t require me to be on my feet plus Im 19 and Im not overweight Im like 6ft and 160 lbs (184cm 72kg). I am fairly inexperienced could that be why? I’ve tried to “practice” by just masterbating standing up (that’s how I taught my self to get use to wearing condoms) but it just really hasn’t been doing anything for me I just slowly lose my hard on unless I sit back down then it tends to come back. Is it worth getting checked by a doctor or should I just keep doing what I’m doing? If anyone’s found ways around this I’d love to hear cause ngl it’s starting to affect my confidence in bed
