Strange sexual side effect

54M was on Wellbutrin for 15 years and has begun having little impact on depression. Never had major side effects on it.

Dr decided to try Auvelity. First couple weeks were awful in adjusting to medicine and how tired it made me but that improved. Now, I am 6 weeks into it feeling much much better.

Only noticeable side effect is during sex. Sorry for TMI. I can achieve and maintain an erection with no problem

My problem….I can not ejaculate!!

With this get better over time? Anything I can do about it?

Thanks!
