Jacking off too much??

Can too much masturbation make it harder to orgasm later in life? I've been masturbating and having orgasms since I was about 7. I'm 19 now and feel like the orgasms just aren't as intense sometimes unless I don't do it as often. Or it takes FOREVER for me to cum which sucks😩 anyone else have this problem? How do I fix it? 
Preferably a way without giving up the only source of sex. Lol
