Talking beyond the whole no sex please thing there are plenty of Ace types out there.
First of all Asexuality it's self has had minor tweaks in its broader meaning but the common and obvious definition is a low or nonexistent interest in sexual relations.
Now from others I have spoken to I've personally noted that Asexuality and the Libido are not one and the same.
EX.
1. A person may be perfectly happy and even enjoy pleasureing them selves, but the idea of someone else getting involved is abhorrent.
2. A person may not have any libido but will engage in sex for the sake of a sexual partner/s.
3. A person may find people 'sexy' in an Asthetic way but not actually be sextually attracted.
4. A person may be with a partner or partners who are both Ace and not
Of course these are just a few examples from personal experiences of other Aces I know.
Why do I personally identify as Ace?
Well it simply is what it is, even before I understood what sex and relationships were I knew there was a key diffrence between me and girls my age. While they where talking about cute boys, or following interest in handsome celebrities I was more interested in other things, what really caught my attention was how different my friend said I was once.
We both loved Sailormoon and watched it together after school at her house or mine. When talking about it once she talked about tuxedo mask and how handsome he was and how she'd marry him if he was real. For my part I was more interested in being Sailormoon, not for the boy but for the adventure, so I could make lots of friends and save the world (at the time I thought if I could be a magical hero like sailormoon I could cure my sister)
She wasn't mean about but did think it was weird that I didn't want to marry tuxedo mask so she asked me who I did want to marry and I told her I didn't know. While part of that could easily be part in parcel of my aspergers that is the first significant memory where I felt different.
For a while in highschool I thought I was gay, I had so little interest in boys out side of anime and harry potter (I'm a Snape simp don't @ me lol) And I preferred the company of girls but, just company. I seriously began to wonder if something was wrong with me, when I met my ex.
That's a story for a whole other time but suffice it to say he convinced me to do things for him I didn't want to do because that's what girlfriends are supposed to do.
It wasn't until my mid twenties that I learned about Asexuality and after looking into it and researching it I realized that it fit me best. After all that time thinking I was broken or weird, discovering Asexuality was a thing took so much off my mind.
How the internet helps and is still helping.
I found out about Asexuality through an erotic role play forum. Not this kind of real stuff but writing kind of roleplay which I started to improve my writing skills. I learned a lot about all sorts of different sexualitys including Aces and Aros.
I learned that the romantic interests in well written characters did not make me anyless ace, because not wanting sex didn't mean not wanting love. By this time I had relocated to the UK and didn't have any real friends to talk about it with. I was able to find all sorts of forums for Ace people and got a lot of support and information.
The dark side of the rainbow.
Finding the answers I had needed had settled a lot of anxiety but it opened the door for a new flood of troubles that I am unfortunately familiar with.
While Aro/Ace people are considered part of the LGBT+ community it was quickly apparent that some people, even in the community saw Asexuality as being not real, and even accusing ace people of attention seeking. I'm used to people claiming my situation isn't real, I'd been putting up with Autism deniers all my life, but I was shoked that anyone in a community that already faced such horrible treatment would so easily lash out at some one just as badly treated.
We as a people have made great strides in bettering things for people who are different from the perceived norm. From better mental health support to different sexualitys being more accepted (obviously theres work to do still but its going) but there are some things that still need a lot of work and the better acceptance of Aro/ace people in general is one of the big ones.
Thankfully finding communitys like this gives me hope that it's happening.
