Low testosterone iusses or just not into me anymore?

My boyfriend claims to have low testosterone.
and we have not had sex because of this. Yet I know he went on a porn site, as I saw one in his history browser. I am hurt and confused and feel so rejected. I mean how would he like if I choose to watch other nude men over having sex with him? I am so hurt and feel so betrayed. I wish someone out there would understand how a girlfriend that has accepted the medical condition of my boyfriend and understood why no sex drive and that was a sacrifice on my part, yet he has be watching porn! I thought having a low testosterone meant no sex drive? I am hurt and confused. He also has stop being as affectionate as he used to be. The 1st year of us dating. Sex was good and offen. Then I got pregnant and he told me it wasn't unjoyable. I was hurt but understood. Some guys don't feel right having sex with a baby in there. Anyways after that it really hasn't been the same. I thought maybe it was I was unattractive to him because of the weight gain. But I have lost 30 lbs since Jan 7th of this year and still losing. Prior to our breakup.(5 days apart, been together almost 3 years ) I had tried seducing him fancy nightie. (As he mentioned sex earlier in the day but the kids were up obviously) Kissed on him even rubbing on him. Let me point out that he was napping on the couch, so he was half asleep. But he didn't even care! I was there trying. He even told me I was pissing him off. So I haven't tried since then. I was so hurt by this. Until last night. As he is back home now (been about 4 days from the 5 day break up) and we are trying to work things out. I got home from work at like 11:20pm so he was already sleeping for about 2 hrs. I had to wake him up to help move his toolbox to my truck for work. When we came in. I Express I had missed him. HE was playing on his damn phone. So I went in front of him and gave him a few kisses. He still didn't get off the phone. I didn't get frustrated I still continue to try. I'm like you going to get off your phone I am trying to give you some love. He said it's 12:30 at night! How long you want me to stay up for. I said not long. Just want some love babe. He said what 2am, me no, what 1:30am me no. So I started to give him kisses all over lips, Cheek, neck, ears. This seem to get his attention. ( but normally he pushes me off) I asked don't you like the happy me and kept giving him kisses. Until well we finally moved to the bedroom. Which was well awesome lol. He doesn't have problems in the bedroom and always can make me happy. So not sure what to do! I know I am very hurt on this. We are trying to work it out. So I don't want to start a drama fight. I have talked to him about the lack of sex in the pass. I always get I am just so tired or you wait till late at night. ( I wait for the kids to go to bed) but now I see he has been watching porn. I found it on his phone a few weeks ago but thought it was spam. but now I saw the same site on his laptop
