Not always - I'm circumcised and and don't use lube at all and everything works just fine. I guess they just sorta messed it up and left me some foreskin? And I would implore you to do some research on the severity of FGM. Just reading from here:

Female genital mutilation is classified into four types:

Type I: Also known as clitoridectomy, this type consists of partial or total removal of the external part of the clitoris and/or its prepuce

Type II: Also known as excision, the external part of clitoris and labia minora are partially or totally removed, with or without excision of the labia majora.

Type III: The most severe form, it is also known as infibulation or pharaonic type. The procedure consists of narrowing the vaginal orifice with creation of a covering seal by cutting and appositioning the labia minora and/or labia majora, with or without removal of the external part of clitoris. The appositioning of the wound edges consists of stitching or holding the cut areas together for a certain period of time (for example, girls’ legs are bound together), to create the covering seal. A small opening is left for urine and menstrual blood to escape.

Type IV: This type consists of all other procedures to the genitalia of women for non-medical purposes, such as pricking, piercing, incising, scraping and cauterization

Immediate consequences of FGM include severe pain and bleeding, shock, difficulty in passing urine, infections, injury to nearby genital tissue and sometimes death. The procedure can result in death through severe bleeding leading to haemorrhagic shock, neurogenic shock as a result of pain and trauma, and overwhelming infection and septicaemia, according to Manfred Nowak, UN Special Rapporteur on Torture and other Cruel, Inhuman or Degrading Treatment or Punishment.

Almost all women who have undergone FGM experience pain and bleeding as a consequence of the procedure. The event itself is traumatic as girls are held down during the procedure. Risk and complications increase with the type of FGM and are more severe and prevalent with infibulations.

“The pain inflicted by FGM does not stop with the initial procedure, but often continues as ongoing torture throughout a woman’s life”, says Manfred Nowak, UN Special Rapporteur on Torture.

In addition to the severe pain during and in the weeks following the cutting, women who have undergone FGM experience various long-term effects - physical, sexual and psychological.

Women may experience chronic pain, chronic pelvic infections, development of cysts, abscesses and genital ulcers, excessive scar tissue formation, infection of the reproductive system, decreased sexual enjoyment and psychological consequences, such as post-traumatic stress disorder.

Additional risks for complications from infibulations include urinary and menstrual problems, infertility, later surgery (defibulation and reinfibulation) and painful sexual intercourse. Sexual intercourse can only take place after opening the infibulation, through surgery or penetrative sexual intercourse. Consequently, sexual intercourse is frequently painful during the first weeks after sexual initiation and the male partner can also experience pain and complications.

When giving birth, the scar tissue might tear, or the opening needs to be cut to allow the baby to come out. After childbirth, women from some ethnic communities are often sown up again to make them “tight” for their husband (reinfibulation). Such cutting and restitching of a woman’s genitalia results in painful scar tissue.

A multi-country study by WHO in six African countries, showed that women who had undergone FGM, had significantly increased risks for adverse events during childbirth, and that genital mutilation in mothers has negative effects on their newborn babies. According to the study, an additional one to two babies per 100 deliveries die as a result of FGM.

Is circumcision damaging to the penis? Most of the time, yes. Can it cause complications later in life? Absolutely. But equating it with FGM is ridiculous.
