Abstinence

Not sure what’s going on but I haven’t had sex in so long I forgot how to do it. The last time we did it I was 6 months pregnant and we stopped because i was having too much pain my son is now 4 months old and we still are not having sex. My drive is high but he’s not interested I found out that he masterbates and that pisses off. I asked him was he gay or cheating and said I was crazy but why are we not having sex. I can’t even remember the last time we shared an intimate kiss or engaged in foreplay. I brought it to his attention so it’s not like he doesn’t know how I feel... this is how people get cheated on...
