Asexuality is a spectrum, so every asexual person experiences it differently. You'll find people who are aromantic asexuals - i.e: they don't experience sexual OR romantic feelings - and you'll find people who are demisexual - i.e: they are capable of feeling sexual attraction, but ONLY with specific people they already have an established emotional connection to. Both fall on the asexual spectrum, but on different ends of it.
Personally, I define myself as a romantic ace - I'm capable of falling in love, having crushes on people, etc., etc. - but I don't really experience sexual attraction. Since the crushes I've had so far have been towards people of the opposite gender, I'm probably hetero-romantic, but I'm not ruling anything out.
I would, yes. I like touch. Holding hands, hugging, cuddling, etc., etc - it's nice. I'm a fairly anxious person, and I find touching someone else reassuring. Never underestimate the comforting power of a really good hug.
Would I be able to have a relationship with someone sexual? Yes, I would, as long as we both clearly understood each others' circumstances and the boundaries of the relationship. I doubt I would be able to have sex with them - but I don't know. As I said, I define myself as a romantic ace, but it is entirely possible I'm demisexual, and just haven't found the right person yet.
As it stands now, though, I would not be able to have sex with them. It would make me feel acutely uncomfortable, and if I wasn't actually experiencing any kind of sexual attraction, I would feel forced, and that's not something you want in a sexual situation.
Nope, sorry, can't answer this one.
I do occasionally have fits of "oh man I'm going to die lonely"-thoughts, but they don't last very long, and they don't hinge on a wish to not be asexual; it's more like I'd like to find someone to be with who would be comfortable with and accepting of my asexuality.
It depends ENTIRELY on how you handle it. It's a dilemma a lot of ace people find themselves with - dealing with other people not understanding/being disappointed by their asexuality - but I recommend you writing a draft of the story and then running it by people who are ace to see whether you've done something offensive or not.
(and note: having a character be upset by your main character's asexuality isn't offensive - it's just an in-character reaction - as long as you don't push the idea that she has a RIGHT to have sex with him just because she's a sexual person; that's not how it works).
I would, yes. Like I said, I like touch, so having the person I love close to me would be something I enjoy. I also require a lot of time to myself - a lot of me-time, a lot of space - but that has nothing to do with romance. I'm just a fairly introverted person who needs a lot of time to myself.
(also, it's "physically")
I have.... no idea what you mean by this? Like I said at the start, there's more than one way to be asexual, ranging from aromantic asexuals all the way through demisexuality and whatnot, and every ace person is bound to be different. Some people are comfortable with touch, some are not. Some people (like demisexuals and grey aces) are capable of feeling sexual attraction, just not with the same frequency or circumstance as non-ace people, and so on.
You'll probably have to clarify this if you want a better answer.
Not really, but then I'm not really out. A few people I know IRL know, and I'm quite honest about it online, but I haven't told my parents. And it's not out of fear or anything - they're good people, they wouldn't mind - it's just that it hasn't come up.
The lack of a love life isn't really as controversial to people as a lot of the other LGBTQ+ orientations. There are obviously idiots who will take offense at that kind of thing, but "sorry, I don't want to" is a fairly non-threatening position in terms of being on the LGBTQ-spectrum.
Not that I am aware of, and you really shouldn't try to make him fit a stereotype. ANYONE can be asexual, and it has NO impact on their general personality. You'll find upbeat, outgoing asexuals, you'll find introverted anti-social asexuals, you'll find asexuals who are everything in between.
