NO SEX 😡😡😡

I had a lost a month ago I've been cleared to have sex since then...2 weeks in my partner and I had sex... I told him I wanted to ttc again he was reluctant... we have not had sex since then...Why won't he have sex with me??? Not even TTC sex I just want SEX SEX....it's a huge blow to my self esteem like what's wrong with me. He climbs in bed and goes right to sleep even if I'm nude, if Im in bed after he works he plays the game or watches TV In the living room. Absolutely No Affection I need to feel wanted...I'm so  "PLUGGED UP" I need sex.. I'm 26 yrs old dude.
