I pretty much only wear women's bikini bottoms these days whether at home or swimming in public. The more feminine the better for me and I really love floral prints, pink or fem colors, ruffles, tie-sides, lace trim, ruched back, etc. I started out with women's bottoms that were more unisex or passable as mens, but as I've grown more and more comfortable with my feminine side I've been wearing swimwear and beachwear that openly expresses that part of me. I also wear women's dresses/coverups and accessories, lip gloss, painted toenails, etc. I don't try to pass as female at all. I basically just want people to know at first glance that I'm a bi/gay sissy bottom, so that's mainly why I wear women's bikinis and swimsuits. Fortunately I have a teeny tiny package that fits perfectly in women's bikinis, swimsuits, panties and other lingerie.
Anyone can feel free to PM me to discuss further!
