Most girls like men who do not wear panties, you are wearing panties. It's the same as not wanting your girlfriend to wear boxers or to dress like a lesbian because thongs and panties are obviously more appealing from the males perspective if you do not prefer he-she's or she-males. Different strokes for different folks, etc etc. There should be compromise, as always, in a relationship - and you should please your girlfriend first and foremost. Mine makes me dress up as a fireman, cowboy, police officer and sumo diaper wearing Japanese commando, I gladly participate in her weird fantasies in hopes that one day she'll grant me a hot threesome with another chick, preferably one that is not extremely obese or a diesel drinking lesbian with a mustache. It's very unlikely, but I always hang onto that small chance since I do please her and make almost all of her wishes come true. I got off track but stop wearing panties and she'll stop making fun of you.
My son, you must inquire which garments your lover prefers. You seem to be strangling your branch and apples in that scarlet guillotine garb, mainly worn by Greek porn actors that dance to house music. Even treasure chests have room for their jewels!
