Girls who’ve had difficulties getting/staying hard. What helped?

So I’ve been on estrogen for 3.5ish years, and projesterone for most of that. I’m about 2 years post orchi. I basically can’t top anymore, and I’ve got two partners that I would very much like to top.

I’ve tried Sildenafil in the past, which did basically nothing. Viagra had mixed results, but leaves a huge barrier to spontaneity. I’ve heard of some girls using topical testosterone creams or gels, but I’m a little afraid of getting other androgenic effects. Kegels haven’t done much good, but perhaps I just haven’t managed to do them consistently enough.

Have any of you had success with anything you’ve tried?
