Search Results: worried about his past

Ok so me and my boyfriend been together for 6 months. He treats me right and all. he's quite an open guy so he tells me stuff like if a girl tries to call him, text him or message him on fb. So anyway, he has told me about his past (his exes and past flings).
there's this girl that he used to have a fling with and she still messages him few times. She would always message him "hey" at 4am. He would respond "hey" back to her but would just exchange few messages (nothing flirty). So today, she messaged him again saying "hey" at 4am again today, and he replied "hey, dont think you should message me again because i got a girlfriend now and im serious with her" and he also showed me all their other messages from last year. She flirts with him (e. g. she asked him to hang out) but he doesn't flirt back and just talk to her as a normal friend. Like when she asked him to hang out, my boyfriend would reply "i dont know I've been busy but ill let you know"
Should I be worried? Should I do anything about it? Why would she text him 4am all the time? So annoyed

Me and my boyfriend have been together for nearly 8 months and we have been intimate for the past 2 months. My boyfriend lives with a lot of housemates (around 6 guys) so when I come over and we have sex, we get distracted by the noise outside and his room is not soundproof so if I moan loud, his housemtes can definitely hear it and will know we are having sex so I try not to moan as loud. So last night my boyfriend suggested this: "babe i was thinking if we should get a hotel room because to be honest, i get distracted and get worried that they will hear us so i can't f**k you right. its only for one night. i just want to spend all day with you for once without anyone else around. we will get a room, go out to lunch then come back to the hotel and spend time together. if you dont want to do this then its fine with me. we dont need to."
I told him "maybe. i will think about it first"
Do you think its okay or shady? I mean I've been with him long enough now and im his girlfriend, but i feel like going to a local hotel would make me feel like a hooker or something. I mean I kind of get what he's saying and yes I dont want distractions either.
So what do you guys think?
