We use the acronym LGBTQ+ rather than longer (eg. LGBTQIA+) or shorter (eg. LGBT) acronyms.
When we want to break down those letters into their constituent parts, we use the terms lesbian, gay, bi, trans, queer, questioning and ace. We prefer bi, trans and ace to bisexual, transgender and asexual because these abbreviations are generally understood to be more inclusive umbrella terms. We prefer not to use the term queer, because although it’s popular with younger people, for an older generation it still has painful associations. The term is potentially also confusing for allies who are still not sure if they are ‘allowed’ to use it.
