As a male married to someone like you, that wants his Mrs to take initiative more here's what I suggest.
1.surprise blowjobs- nothing makes a male more happier than one of these.
2. Dress up and wait for him to enter. Because you have already dressed up he knows what is about to go down and will pounce on you. You just need to make the first move which is dressing up.
3. Tie him up and blindfold him. If he is tied it gives you a chance to take advantage of him and show him your dominant side. If he is blindfolded he cant see you, meaning you don't have to be as nervous. Even gag him so he cant say anything, let it be your time to shine.
4.when he is relaxing rub his balls. Males love getting their balls rubbed and there's no better way to show your appreciation than you rubbing them whilst he is at home relaxing. The next time he is sitting up having a beer and watching tv just put your hands down his trousers and rub his balls.
5. Strip down and wait for your man on the bed head down ,arms flat infront of you and arse up. Its a very sexy sight to see and again that's all you have to do to initiate it.
6. Surprise him with a porno movie. Watching one with your partner is always fun and it shows him that you are confident and that their is trust in your relationship. It normally leads to sex.
7. Talk dirty. You don't have to go porno script on him. Just tell him things you like and fantasize about. For example if last week he stroked your genitals in a way you liked. You look him in the eyes, bite your lips and say i loved the way you did that "....."whilst rubbing your hand over his chest or over his trousers. You will get him.excited to do it again.
the main thing to remember is to communicate. If you liked something make sure he knows. If you fantasize something make sure he knows. if you want something, you get it. Communicating builds trust and leaves to you being more confident with your OH
