Dick grows huge

I'm sure my dick has never increased in size by as much as yours does, but I've definitely observed something similar, and I'm willing to believe you might be as much as a fifth bigger because people vary.

As for why it happens, I don't know for sure, but if you're talking about seeing the increase in size following penis-in-vagina sex, I suspect it's largely due to prolonged stimulation that feels great but isn't as intense and tightly focused as what you do to yourself when you're masturbating.

As for whether Viagra or some other erectile dysfunction medication would have some effect from the start, I have no idea. There's only one way to find out. However, I would suggest that you do a little research before you buy some blue pills. Cialis works just as well for most guys in terms of results, and the effect is much longer-lasting than Viagra, so you don't need to pre-plan quite so much.

I find it interesting to think about sex in evolutionary terms, From this perspective, it's not difficult to see how there might have been some evolutionary pressure favouring males whose penis grew in size during intercourse. Not being so huge that penis entry was painful for the female would result in more opportunities to mate. Getting larger in the vagina would help ensure a snug fit that ensured that semen went where it was supposed to go. And since it seems likely that the glans (a feature of the human penis that no other animal has) evolved because it very efficiently removes any semen already in a vagina, this increasing in size would increase its efficiency.

I think it’s normal to have just average erections and other times when it’s so crazy hard you think the head’s going to explode. That gets to be less frequent as you get older. You should talk to your doctor if you want to try Viagra for it.
