I'm having desire issues, like lacking the desire to do "it" however, i still try to do it once a day or?

This is so messed up! You had two children with a guy who pressures you ually, and you've tolerated this loser for 5 years. Any relationship in which one partner pressures the other to behave in ways with which she is not comfortable is not a healthy relationship. It's bizarre that you would choose to have kids with someone like this! Did you really want such a selfish boy as the father of your children?
