My brother freaks out if he sees me in my underwear

Your brother secretly wants to sleep with you.

Its just brotherly love. Brotherly love in the sense he doesnt want to see his family members nude or semi nude. Hopefully its regular brotherly love and not baton rouge brotherly love. He just doenst want to get them impure thoughts ill tell you what.

i love to walk around in sexy panties

Stop putting your brother into temptation

Your Brother is actually scared that he is going to pop a boner when he sees you like that...

I don't know, doesn't seem to normal to me. Maybe he gets hard seeing you in underwear but then there would be a similar problem if you were wearing a bikini or something. I don't mind seeing my sister in only her underwear and neither does she. After all, I'm not attracted to her in the least and don't get a boner by looking at her.

Women in panties are normally showing less skin than they would be in a bikini, but it's more intimate.
A woman in a bikini is usually at the pool or at the beach, in a more public setting and she is usually dressed that way for swimming or tanning or just showing off.
Panties are more intimate and personal and more commonly regarded as bedroom attire.
Either one would make me hard, but if a girl was prancing around in front of me in her panties I would regard that as an invitation to respond in some way, at least with my comments. If she was in a bikini under the same circumstances I might take it less personal.

Love it of you walked around me in panties

Would have to agree he gets turned on seeing you in them,probably thinking about licking that beautiful sweet tasting thing ;) ok I am thinking that lol,but I am sure he is to

He may have a "thing" for women in their underwear. It's a very common fetish (shared by yours truly), and it bothers him that seeing you excites him.

He would have been really uncomfortable in an old girlfriend of mine's family. They all paraded around in their underwear, including her mom and her sister, even though they knew it got me horny. I was sure her mother enjoyed it. "Lisa" once told me that even though her mother was totally devoted to her father, she was a bit of a "submissive" and enjoyed turning me on. She had some sort of "daughter's boyfriend crush" on me. I didn't mind. He mother was very easy on the eyes.

You should be naked around him all the time.

You're 23. This shit stopped being appropriate 12 years ago. Either go put on some pants, or give the poor warped boy some ass.

he gets hard and dont want you to see it he might jerk off after thinking of you

I would put money on the fact that he has some desires for you and getting an erection you might see and think he is weird or freaky ...a lot of males go through this...

Women looks good in white camisole and black underwear. Bikini actually annoys me.

Its a little embarrassing for him to make a big deal out of it, not to mention controlling for him to tell you what to do. If he doesmt like seeing you like that he should just leave the room.If he is concerned about other guys treating you a certain way he should just talk to you about it.Hes embarrassing you and making you self conscious when its really his problem not yours . Tell him how you dress is your concern not his and to mind his own business, you dont tell him how to dress.

Maybe he doesn't want to walk around sporting a huge boner.
