Someone who is unconscious, or cannot be woken

Is any of this happening?
Be seen today
Seek urgent mental health support, however, if distress about sex or relationships leads to thoughts of self-harm or suicide.
3
Does any of this apply?
Book an appointment
Arrange a routine appointment with a primary care or sexual health professional if early ejaculation happens repeatedly, causes distress, affects a relationship, or makes you avoid sexual activity.
You can also seek help simply because you would like treatment; the problem does not need to be severe.
Routine assessment is especially useful if the problem started suddenly or occurs alongside:
Difficulty getting or keeping an erection
Pain during ejaculation
Pelvic, testicular, or genital pain
Burning or difficulty when urinating
Blood in semen or urine
A major change in mood or anxiety
Every sign above is quoted from the sofidex article on Premature ejaculation. If you are not sure, err upward — it is always reasonable to be checked.
