I am feeling a bit unsure about how hard to push for sex and how to determine what is a success and what isn't.

I've been trying to gradually flirt a little more with my wife, grabbing her ass, sending a sexy text message, making comments in passing. But I feel like these efforts have mostly been met with annoyance.

The most recent example was yesterday. Wife is just entering her fertile period, so I figured she would be more receptive to my advances.

I text her "I can't get your beautiful ass out of my head today ;)"

Her response: "Ok." "I get it." "Loud and Clear."

I don't respond further.

That night we get in bed and I initiate. She acts annoyed, but takes off her pants and we end up having sex. She is totally starfish for the whole thing. Not engaged at all. Definitely no orgasm on her part.

After I finish we're laying there and I'm touch her and she says something like "You got to cum, isn't that what you wanted. I'm tired and exhausted."

I'm not sure if this is progress or not. Doesn't seem like she is attracted at all or interested -- just seems like my initiation is making her feel like she has to have sex with me. I have been as OI as I can when she has refused me recently and haven't even brought up sex other than when I initiate it or try to make a seductive comment during the day.

Obviously you can't negotiate attraction, but despite us having more sex she seems to be treating it like a chore. Would it make sense to not initiate as much? Am I pushing too fast without having increased my SMV enough?
