My friend lost her virginity to her bf with large penis and said that hurt her really bad and have a lot of stretching and tearing feeling down there. She cried when he enter her. She told me that he bf size is about her 3 fingers wide. I started to worry my first time sex as my bf is bigger than that. She ask me to plan in more margin of stretching and tearing pain since he is so big. I would like to look for advise from somebody lost her virginity to a big size and share her feeling.

The problem may not lie solely in his size. Perhaps your friend wasn't properly lubricated. Oral sex can help with that, but sometimes that's not enough and a water-based lubricant might need to be used. You should try the lube your first time, just in case, and then in the future you may not need it.

I would suggest he does not penetrate until you have done at least 60 mins of foreplay to flood the pelvis with large amounts of blood to allow easier stretching. The hornier you are feeling, the more natural lubrication there is in the opening of your vulva and vg.

Artificial lubrication can help, and fingers need to be clean if there is tearing of skin to heal afterwards.

Guys should rub a lot of lubrication onto their penis.

When a woman has a baby, the labour of pushing out the baby takes up to 14 hours, because of the stretching and relaxation required of the vagina and vulva - there is a big flow of blood through the area.

Dry stretching is painful. They used to call it a "chinese burn".

Some women do have fast births, but the labour has been silent and not felt, but the stretching has still been going on.

Birth is same as a vagina - needs a lot of lubrication. You need oil in your car to stop the bearings jamming and wearing out. A playground slide would burn your skin if it was not a slippery surface.

A penis won't slip into a vagina if it is too dry. Inside a vagina might be quite roomy, but the vulva could be very tight (and anti-men).
