I think we all have things like that. For me, I was very worried about sticking someone with a needle, and putting my fingers into someone elses's body. Three years ago if you had asked me about those two things, I would probably have said that they were big issues for me but I was hoping I could get past them and become a midwife anyway. Obviously, I did. Suturing was easier for me because I didn't do it until the very END of my training, and because I had seen quite a few in the course of the previous two years. I had also learned to draw blood and give injections, so I was over my fear of sticking someone with a needle by then also, which made suturing easier for me.
By the time I started doing vag. exams, I had witnessed so many of them, and done more than a few paps, that it wasn't something that freaked me out anymore. The observations and paps were the baby steps leading up to the vag exam and it seemed like a natural progression.
I think a good teacher will ask what your biggest concerns are regarding midwifery skills and will work with you to get through them.
Fortunately, suturing isn't something you'll have to do a whole lot, so you don't have to be 100% comfortable with it. As a client, I'd be worried about hiring a midwife who ENJOYED suturing
