I'm going to pressure my wife about sex
Why have you felt like pressuring her about sex?
I'm feeling a little agitated with the situation. I think it's been a while since we've had sex
Pressuring someone for sex will make her have sex with you when she doesn't want and she won't enjoy it. It would be better to talk to her and ask her what she needs in order to have more sex. Does she need more romance or something else?
I guess it will make her feel more eager to have sex with me.
It would make sex more enjoyable for the both of you to have both of you want to have sex. It would be good for you to have more conversations with your wife about things that you both want so that you are on the same page.
