Is it normal to be rejected for sex or why is he making excuses?

5 yr relationship. he's going through a lot in his business, major life issues. Oh he's older man like 50 and drinks

Lately I've caught him lying to me about hos plans, schedule and whereabouts.

Mostly to avoid seeing me for sex. he's an avoidant personality. We had great sex last Sunday 2x then I was supposed to see him wed. he's texting he's sore, it feels like a burn. Um, ok. he's more sometimes because he's not circumcised but 2 days later?

Wed comes around and he gives me some bullshit excuse he can't see me and lied about what time his Thanksgiving flight was wed eve. So he's out of town with his kids till Sunday. Then I catch him lying about his plane arrival time. Oh he's coming in very late. I say skim going to Sam's, he says what time. ( meaning he wasn't coming back as late as he made it sound) I said now, he says oh ok. Then he says oh im sick im on an antibiotic. Antibiotics usually effect him like Ed. No idea why he randomly told me he's on an antibiotic. Everything is fine. He just paid my 1200 car repair bill, we sre making plans to visit a swingers club. What im going to do is not see him on our usual days this week. Just tell him last minute, lets just meet wed. He will ask why im just saying I don't know I need space. Anyone know what's going on with him? I dont think he's cheating.
