Sex-lacking Marriage

My husband and I have been together for over 6 years now- when we first got together the sex was good, he’s never really been able to last very long and he’s always been very self conscious about that- but it never really bothered me and I made sure you reassure him of that. We’ve never really been the type of couple who has super spontaneous sex and the only other place sex has happed outside of the bedroom is on our living room couch 😑 when we were trying to conceive our first born I was very adamant about making the first move because I knew when I was ovulating and what not and he never once turned me down but he also never really initiated sex. Our daughter is now 2 and I can count on my hands how many times we have had sex since she has been born. It’s like his sex drive has vanished! We’ve spoken about it several times and he’s blames it on stress, or work but I can’t help but feel inadequate. I’m a pretty sexual person and enjoy sex but it just seems like he’s never really into it and always embarrassed every time we do do it.... I would love any advice- he’s agreed he would go see a doctor and get his testosterone levels checked but his job makes it difficult to actually do that so he keeps putting it off! WHAT DO I DO IN THE MEAN TIME BECAUSE MAMA REALLY WANTS SOME SEX 😩
