So frustrated and he knows it

Alright guys , let me know what you think .

Me and my man have been dating for almost 3 years and have had a VERY active sex life in the past . Recently , within the past 6-8 months he hasn’t wanted to be sexual or to have sex as often . It’s not to the point where it’s unbearable but it’s been bothering me enough. We have discussed it and he said he simply isn’t in the mood as much anymore . I’m not worried about him cheating on me or anything , i just want to know if any of y’all have experienced the same thing . I’ve tried to spice things up , make it more interesting ect.. but nothing is really working 🧐🤨 of course i respect that he doesn’t want to be sexual all the time . It’s just frustrating being the only one who wants it . And he knows all of this . I just don’t know what else to do . I can’t make myself not want him
