What causes micro-perforated hymen?

Hello doctor,

I think I have a micro-perforated hymen. I have just taken photos of my hymen and it appears to have a micro-perforation as I can notice a small hole and the hymen is bulging out. However, I have noticed a couple of differences that may not be considered while identifying a micro perforated hymen.

1. The hole is towards the back of the vulva, not in the middle.
2. There appear to be a few curvy lines or wrinkles towards the front or middle of the hymen.

There never seemed to be any problems related to menstrual cycle and bleeding. When I started getting my periods, it was difficult to use tampons, as it felt like I was hitting a soft piece of skin during insertion. When I had to use them many times during dance competitions, my mother forced them inside and she felt a lot of resistance. It hurt a bit and I could feel the tampons in me the whole time, even though I was using the smallest type. It was particularly painful to take them out even though I was slow and gentle. I tried inserting a couple of fingers inside, after being sexually turned on with success, but I definitely have to move past and stretch the hymen to do so. It was initially impossible to insert a larger dildo, but I managed as I gradually increased the size of the dildos I used. However, the longer I go without using them, the harder it gets and it can sting a little bit no matter what.

When I was born, no abnormalities to the hymen were detected, but the doctor detected a slightly soft skull and an unusual curve to one side of the skull. I do not recall any injury or infection to the hymen or vulva, but I did not tend to respond to pain or express much emotion as a young child, even in circumstances where I was hit quite hard. I also recall experiencing pleasure from physical pain at the age of three to four, so maybe I would find hymenal tearing or discomfort insignificant enough not to express pain or talk about if it did happen at some point. I did get chickenpox in almost every region, including around the private area, although I am not sure if any were present close to the hymen.

I also used to masturbate to the point of orgasm every other day between the ages of about three to five years. I have a feeling that the hymen could have thickened since it is often developing at that age and maybe the orgasms were powerful and frequent enough to close up the hole a bit, but does that occur? Following are certain concerns about my hymen.

1. Can the vaginal opening of a micro perforate hymen be towards the back of the vulva rather than in the middle?
2. What does it mean, if part of the hymen is wrinkly, in a young adult?
3. What would have happened to my hymen during the development causing a micro perforate hymen?
4. Can chickenpox on the vulva cause this?
5. Can frequent masturbation to the point of orgasm as a toddler cause this?

Kindly suggest.

Thank you.

Hello doctor,

Thank you for the reply.

I cannot describe the size of the perforation, but it is much smaller than normal and seems to appear similar to other micro perforate hymens I have seen. The hymen is probably softish but very thick and I had no known infection or injury. I have regular periods.

Thanks.

Hello doctor,

Thank you for the reply.

I have good blood flow during my menstrual cycle, but it tends to flow almost up to my back when I am lying down.

Thanks.

Hello doctor,

Thank you for the reply.

That was very helpful.

I just want to know if there is any difference between the appearance of a micro perforate hymen that is present at birth and one that is caused by injury or infection.

Thanks.
