I have a hard time climaxing with the guy im talking to (20m)

I feel so dumb even writing this but i dont really have any close queer friends and i do not think that my female friends can relate to this as much as i would like to lmao

Im casually talking with this guy my age for over a month now that im really attracted to and even though its probably not gonna turn into a relationship due to the fact hes bisexual but openly told me that he prefers women and he cant see himself being in a relationship with a man im still having lots of fun just hanging with him and sharing our interests with each other

The only problem is that...hes really not that good in bed? And i absolutely do not wanna shame him but i really am not that hard to please. Most of the time im content with not climaxing and i get off by seeing someone actually enjoying themselves due to me servicing them but its just gets boring after a certain point you know? Hes not a great kisser (god forbid that man would ever slip some tongue or anything) and i thought for a second that maybe hes that way because im not a woman and he doesnt find me attractive but after hearing his story about getting ghosted when he had a making out session with a girl im starting to believe that it is his usual performance, Hes not completely overlooking me during and i can see him trying to please me but for some reason its absolutely not working and even when im actively jerking off trying to climax it just doesnt work at all and its making me feel a little ashamed? And it feels like i cannot blame him for being that way and he always asks to make sure that everything is okay during sex but it is kinda embarassing to bring up this topic when its not like we are a couple or smth

I even thought that maybe I was the problem here but recently i did had sex with another person and didnt really have any problem climaxing so it really is possible i guess....

I just feel so dumb cause i really wish i couldve had a better sexual chemistry with this man
