Haha no worries <3
I am asexual; I've been in two (serious) relationships before and neither of them were of the same sexuality as me. Neither of them ended because of sex-related reasons actually and my most recent bf said I'd 'turned him asexual' because he literally didn't care about sex with me and was veryyy happy.
For the majority of people I think it would be an issue ultimately (I think it would've been with my first ex too) and I don't expect to ever be in a long-term relationship tbh but I'm willing to date anyone who is okay with it (if we're attracted to each other etc).
Hmm, long answer there
But basically it's just a relationship without sex.
