Mayor issue

So me and my man have been together for almost three years. 
The thing is my BF wants me to give 
him blow jobs, which is only fair as he goes down on me. 
I'v never been fond of dick face action. 
Also having a hard time touching him, as sperm as always been eww factor for me, hate the feeling of it. 
I'm 24 years old and its breaking my heart cause I want to get passed this, so that I can please my BF & be the girl he loves 
Feel so fucking stupid!
