The 22-year-old has a rare condition, which means she has been permanently sexually aroused since the age of eight.
A simple vibration from a mobile phone is all it takes to push Amanda's buttons.
Loud bass music in a club and travelling by car or plane can also trigger the unusual response.
And it can happen absolutely anywhere — when she’s with her friends and even while she’s at work as a sales associate in a baby products shop.
But far from being a blessing, many who suffer with the condition believe they are cursed.
Last year, 39-year-old Gretchen Molannen, from Florida, committed suicide after battling the condition, known as Persistent Sexual Arousal Syndrome or PSAS, for 16 years.
The news was particularly difficult to take for Amanda, who was also from Florida.
She said: "It is not pleasurable, you could say it has become a torture. This condition controls your life completely and it is like living a nightmare. I can have 50 orgasms in one day and five or ten within an hour of each other.
“It happens when I’m with my friends or out in public and it’s very embarrassing. It kills me inside. I just have to put on a smile and pretend that nothing’s wrong.
“Orgasms are supposed to be a good feeling but I’ve had them every day for so long now that I’m living with constant fear and shame.”
She added: “At my lowest points, I have thought about suicide but I had to reassure myself that I would never resort to something like that and that it wasn’t going to happen to me.”
Amanda first began suffering from the condition when she was just eight, but was too scared to confide in anyone.
She said: “As a child I had no idea what was happening to me — I thought I was just sex-obsessed.”
It wasn’t until 2008 that she learnt about PSAS by hearing a discussion about it on the radio.
Since then she has tried to move on with her life and, at 20, even began dating, but she admits she has not been able to have a steady relationship — because men either take advantage or are intimidated.
She said: "I’ve been with a few guys, but it’s difficult - I’ve found some guys are even intimidated.
“Thankfully I’ve had the courage to tell my family and they have all been very understanding and supportive.”
She added: “I get people say I’m making it up and that I’m really a nymphomaniac but I don’t let it phase me.
“I just now hope that there will one day be more understanding of this condition and my story will give just one other person the courage to get support.”
