Hi Daisy,
I'm Jeanette don't think I've talked with you before so welcome and Hi. I'm a bikini panty girl myself. as long as the gusset is wide enough to hold me in that is. I've tried some boyshort panties and though I like the look they don't seem to fit on me as they appear to on the cis-women in the pictures. As a result they don't want to hold me in as one would think they should. I believe it is the different in hip and thighs. Maybe somewhere down the road when I've been on HRT long that will change. Hmmmm come to think of it with the changes I've seen already they just might fit better....
Hugs,
Jeanette
