What's that one se#ual act which you just do for the sake of your partner's happiness?

Eat her during her period

Explore her wants and do my best

Ex of mine used to ask that I wear panties

Being submissive at my wife's request.

I tried letting my then partner have anal sex with me just to make him happy, but it didn't work out right.

All of them ☺

always make sure she cums first no matter what sexual act it takes.

I always went down on the love of my life. It made her happy and I was happy to do it. In the eight years we were together, off and on, I got one blow job.

My husband has passed away now but everything I did was for his happiness. That doesn't mean I didn't get enjoyment too.

I mean to a degree, it's going down on him because I don't get physical pleasure from it, he does. I do it often so he is usually always happy lol

Anal is another one I do once in a while just for his pleasure. I've never been a fan of it overall lol

It isn't a current partner but I had a partner who wanted to be dominated in bed. I am more apt to be nurturing in bed making it feel awkward for me to do.

We dated for over a year and I was pretty consistent about doing what she wanted but I was off-balance mentally.
