Oral sex is stressful with my partner /u/throw-awaysexgirl Sex

I’ve (21F) been in a relationship for a few months with a new partner (22M) and it has been very difficult for him to get me to climax. We’ve had sex dozens of times but I’ve probably climaxed less than 10% of the time. I thought maybe with more practice and experience it would be easier, and I can tell he has gotten better, but I still struggle a lot. I feel like I go through waves where it gets closer to feeling like I’m about to come, and then something happens whether it be a change in the movement, or an external factor (like noise in the hallway) and that edging feeling just disappears completely and he has to start all over to make me feel good. Having him go down on me stresses me out because he will go down on me for close to 30-45 minutes sometimes with no luck, and he insists on wanting to get me there and have me feel good, but it still feels like something is missing and it shouldn’t take this long. I feel bad because I know he’s expecting me to climax, and then I overthink it and it makes me stressed out and unable to fully enjoy it. Having him go down on me for long periods of time also draws me away from the excitement and passion that leads to us having sex, and it becomes unexciting laying down for that long. He also doesn’t really interact much when he is going down on me, so it just feels silent and lonely during that time.
Some things to note:

I am on antidepressants and have been for 5+ years I have been able to climax slightly more often and in less time with past partners, though not more than half the time even with them I find it easiest to climax when I am extremely horny and moving a lot while in the moment I am able to climax most of the time when masturbating, though it can take 20-40 minutes

I guess the main issue is I just want to be able to climax more often and not have him or me be stressed out by it. Is this something I should address with a sex therapist or even my psychiatrist instead?
