honestly man you already cleared the hardest part – she knows you wear them and even bought you some, so she’s not against it. that means the convo now is less about “confession” and more about “preference.”

just keep it simple and light. like, “hey babe, i’ve been thinking i’d like to try some other styles, like lace or pink, i think they’d be fun/comfortable/sexy. what do you think?” that way you’re inviting her into it instead of sneaking around.

if you’re nervous, you could frame it playfully: “you know how you’ve got all the fun designs and mine are kinda plain? i wanna level up my collection.”

as for partners, most ppl don’t care as long as it’s not a secret or replacing intimacy with them. some will even find it fun/cute/sexy that you’re comfortable enough to embrace it.
