Sex Anxiety

I’m a mid 20’s male who’s always struggled with escalating into sex and I’ve had a hard time understanding why I’m like this. For context, I was a late bloomer (lost my virginity at 22) but generally not nervous talking / flirting with women. The first two women I ever slept with I had difficulty staying hard and it kind of chipped away at my confidence. Got blood work done and determined I had low T levels but i’ve tried reversing that through diet & exercise (now in the 500-600 ng/dcl from low 200’s). For the guys who have experienced something similar, how do you get over the anxiety leading up to sex? I can’t help but think of the times where I didn’t “perform” and I’ve thought about just getting a prostitute to get the rust off. Kinda extreme but just curious how y’all have gotten rid of the nerves, thanks !
