Not TMI bananaToffo - a very important issue!
Some women find that increasing oestrogen alone can imrpove libido and sexual response if sufficiently high enough.
Oral HRT is known to decrease libido due to increase in SHBG which binds free testosterone make it less available.
Progesterone and synthetic progestogens have a sedative effect and some also have a dampening effect on libido so continuous combined HRT (prescribed to post-menopausal women) is not ideal.
Some synthetic progestogens that are derived from testosterone ( eg norethisterone and levonorgestrel) can improve libido in some women, although others find the side effects too much to contend with.
Medication such as some anti-depressants can also depress libido.
It is important to have adequate oestrogen replacement before considering adding testosterone - you don't want to become T dominant. As has been said the only formulation licensed for libido in UK is Tibolone for post-meno women and some find the oestrogen dose in this not high enough. Some NHS GPs (such as mine) and many private gynaes will prescribe testosterone off licence using gel products designed for men (Testogel, Testim, Tostran). There is a very expensive T cream for women - Androfeme - available in Oz and which some private gynaes in UK import and prescribe, but this is out of reach for many women due to costs (of consultation and prescription).
I have been on HRT for 11 + years and T replacement for 3. My O's were pretty much non-existent at the time - but response is amazing again - and they are now better than they have been for many years, although libido is pretty much unchanged.
As has been said - you need to deal with VA so at least when you do have a go it is comfortable - but for me adding T was key to enjoying it all once more
