So I’m a virgin in my early 20s, but I have gotten head like 20-30 times. First I have a problem getting hard. It takes a bit of stimulation and when I finally do get an erection it goes down as soon as the stimulation stops. Also I usually only last around 2-3 minutes from head. Has anyone been in a similar situation? Is it maybe cause I’m a virgin? What can I do about it?
