A man releases semen when he reaches orgasm after sexual activity (including masturbation).
When a male releases semen, it is called ejaculation.
Ejaculation is when a man reaches orgasm and releases his sperm-containing semen.
When a man ejaculates, also known as "coming" or "cumming," it means he releases semen from his penis. This is a normal biological response during sexual arousal and orgasm.
As long as the man is STD free swallowing semen will not hurt you. A 51 year old man is not different than a 21 year old. The woman's health is not compromised by the age of the man.
No, it does not hurt. There is a strange sensation which is enjoyable. The more often the boy masturbates the more enjoyable the ejaculation of semen becomes.

Unless it has an STD, then no it is harmless.
