For those is long term relationships, what are your partner's "weaknesses"? What do you do/say to turn them on immediately? If you want to make them cum as hard as possible, what do you do to them?

A couple days of no stress usually does it.

I've been with my wife for 18 years. So far the only way I've found to do any of the things mentioned by OP Is the above post.

The more stress I can remove from her life, the more energy she has to focus on herself and things she'd like to do, instead of things she has to do.

Luckily I have only to ask, to get some. We have a compromise up not down policy so if either of us wants sex we do it.

He says when I move back against him in doggy is what he can't resist, also telling him about guys I've done stuff with (real or imagined) is a slam dunk.

For me it's always been rough stuff, make me. That is the quickest.

I love the question!

I think my partners weakness is, when I come to him and just take his pants of without any warning, because I want to give him a blowjob :3 Or when I tease him with my body so he knows I want to be fucked :3

What I also started doing lately, and he absolutely loves it, is caressing his penis while giving him blowjob. Kissing it, licking it, showing care <3

And I can't forget about my progress with anal, he cannot get enough of it and I also find it pleasurable! :3

I enjoy his beautiful body and giving him pleasure so much! :3

How and/or why is this comment causing this much sexual arousal by being this wholesome? You seem wonderful.
- I'm glad you liked my comment <3 It really all comes down to communication and healthy sexuality, it's amazing trying new things and just having fun with it all.
  
  Thank you for such an amazing question! You seem really wonderful too <3
Damn. Never get married lol

Last relationship was to make a light dinner like a salad and then massage her while telling her we wouldn't have sex that night. Just intimacy, no sex. She'd always have to prove me wrong.

Current relationship is simply grabbing her throat or her hair and forcing eye contact. She instantly turns into a complete slut.

Well, that escalated instantaneously.
- It's quite the adjustment for me as you can imagine. Some women like to be teased and tempted others like to be dominated. Just don't mix them up right?

There isn't a single weakness that I can name, nor do I know I can always turn her on immediately. If she is turned on though, talking about her getting fucked by another guy or a guy going on me does the trick.
