I (23F) feeling like I’m begging to feel desired by my boyfriend (24M)

I have voiced concerns several times about not feeling desired by my boyfriend and feel like I compliment him and voice my desire for him way more than he does. I have to keep in mind that he is under a lot of stress and isn’t in that headspace at the moment but other than a “you look good/cute” there isn’t much coming from his end. I don’t expect him to be horny for me considering all the stress he is under but I wish he put in the same effort to make me feel good that I do for him. Especially when I have voiced this feeling many times.

I get being overwhelmed but I dont understand how that translates to not voicing much attraction to your partner. I know that I am personalizing and letting my insecurities cloud my judgment but at the same time there are moments where I feel as if I have to beg or just compliment him so he compliments me back. I know the distance has a lot to do with it and can make it hard but the last time I saw him I brought lingerie to wear for him and when I put it on all he did was say “you look sexy”and go back on his phone.

I have already bugged him about it enough times to bring it up again so I am here asking for advice and or tips on dealing with insecurities in these situations. The only thing I can think to do is get used to it and work on not personalizing.
