I am noticing genuine progress in my back with my weight lifting and I’m SO happy!!
I used to be 262 pounds and now I’m down to 190lbs and began my weightlifting journey! Now I can take these photos confidently :)
My(20F) partner(21M) can’t seem to stay into it after he’s finished, like basically it goes from 100% to like 3% effort. He will be railing me and saying the dirtiest things I’ve ever heard and then once he’s finished it’s like.. nothing? He starts to not even be able to thrust he’s so tired.
After he finished usually he switches to eating me out or fingering me which is.. not so great after he’s done because he doesn’t EAT IT eat it you know? But when it’s beforehand he goes to town and it’s extremely arousing for me.
I’ve tried like being dominant with him and doing the whole “you can’t cum before I do” to see if that helps but he ends up finishing and I have no idea that he came until yknow the immediate switch to 3% effort.
I’m flattered that he cums so fast, but I have talked to him a lot about it to try and find ways to keep him from cumming before I do, but he seems to do it anyway? Maybe it’s involuntary but I don’t really know.
Maybe the problem is I’m taking too long to cum myself, but honestly a lot of the time I’ll be super close and then he switches to 3% and then now it’s takes even longer or a lot of the time I don’t get there at all.
Any advice? He’s a fairly overweight guy and he says that’s the reason it switches so fast, but he also refuses to like eat better and workout with me, and I refuse to believe there’s no hope.
