I do wear both, but i perfer wearing pantyhose mostly. I tuck when i dress fem. I really love how it feels and tucking in pantyhose creates a very smooth front, and keeps me secure tucked away compared to alot of panties.
pantyhose, or even better, full nylon bodystocking. i have a tiny penis so i don't really need to tuck - the bulge is barely visible. nylon group sex is the best sex.
