Need advice

Okay so my husband was out of town for work for a week ...we were having issues with him not having energy to having sex . He is always exhausted and is no longer in the best shape so he feels self conscious but it's been making me feel very unattractive when I want to sleep with him and he doesn't ever seem to want to . Anyways he just came back from his work trip last night and I wanted to see if he's been talking to anyone else cus now I'm just getting very insecure . Didn't find any odd texts . In his history I did find a shit ton of porn that he doesn't want me looking at ..,also found a hook up request . He swears up and down that he didn't cheat on me and that the adds just pop up . Wouldn't he of had to click on the hook up request for me I be able to actually see it in his phone history? I'm just really confused and hurt and feeling so unattractive and I don't know what to believe now .
