Is it normal to be uncomfortable near brother making out with finance?

As a Star Trek fan, I find that appalling! Anyway, yes it is very rude for them to have so much PDA, especially at that age, they're not kids after all.

It would be rude if you made it clear it bothered you. Simply explain that their displays of affection make you uncomfortable and, if they are going to carry on, they do it when you aren't around.

However, you don't mention why both of you (and the girlfriend) are around together (do you live together?) or who is paying the rent.

If your brother (or he and the gf) is paying, you are in THEIR home ... and it might be YOU who needs to find another place to go (to watch TV).

If you are equal roommates, you need to set up some rules.

If you are mooching or just hanging out there, you don't have a leg to stand on.

Immature people make out when other people are around. It is just so un necessary and anyone who disagrees is, well, immature.

Can you watch tv elsewhere? Can you ask them to knock it off because you don't want to witness it?

I am a firm believer that there is a time and place for everything. Making out in front of people is just stupid. Tell them to stop.

Given you are uncomfortable with this public display of affection, you need to speak directly with your brother and share with him how this behavior makes you feel, emphasize you have no issue with affection but it is not appropriate to do this so openly and deliberately in front of you when you are all in the same room. Ask him to respect your personal boundaries as you do his.

Hahaha! Nice! This is what I would do- when they start making out or whatever, look at them and say stuff like "Hell yeah!", "Daaaamn!", and "You guys are starting to turn me on with all that." in a horny/dirty old man voice. Do it just to mess with them and perhaps embarrass them/ruin the moment enough to make them stop. Other fun things you can do: Get a (video) camera, pause the show and leer at them silently with your mouth hanging slightly open, start (pretending?) to take off your pants, pull off your shirt, wave it around, and yell "Partaaay!", applaud, turn off the tv abruptly and walk away, saying you have to go "take care of yourself" and "it's all their fault!", pant like a dog, turn the tv way up and go sit/stand really close to it, and whatever else you can think of! See how much fun you can have with this? Now I wish I was in this situation! :D

Hell no that's rude! they should be more considerate of you, make them leave or just go somewhere else if they keep doing that.

He's 26?!?! Tell him Jr. high ended a long time ago.

maybe you should move out so you can watch tv more instead of them

yeah, especially when you want in on the action. ask nicely.
