Debbie downer boyfriend

Anytime I want to do anything with my boyfriend he always makes the excuse that he isn't feeling well and just wants to lay around and nap. Today, all day he slept in my bed and did nothing and I know he isn't sick. He just laid around and watched movies and stuff on his phone. Then we had sex, really intense fun sex. he came and I almost did, but he stopped right before I could. So I asked him if we could go to the sex shop and get some new stuff and have some more sex later and he ALL OF A SUDDEN doesn't feel good and won't go with me. I'm so upset. I'm sorry I just had to rant because now he's sleeping and I just wanna go taste test some new lubes. Ugh, rant over
