Im 20 years old and I've never cum consciously in my life. I've tried jerking off before and it feels good but I can only go 10 minutes before getting bored and just stopping so I never did it to the point of ejaculation. My testosterone levels are solid and I get wet dreams regularly where I do ejaculate. Normally I wouldn't care but I've been seeing a girl recently and we're planning to have sex in the near future and I'm worried that I won't cum and it'll be embarrassing as hell for the both of us. She's given me handjobs before but it still doesn't do the trick for me which is adding to my anxiety. Is there any way to resolve this issue?
