Help, need advice


Ok so I'm a little embarrassed to be posting this but I need advice. I have been with my husband for 6 years when we first had sex I was able to have an orgasm. But after that we lived with my parents and didn't have sex often. I got used to having an orgasm by being fingered. now we have been trying for a baby for a year and everything I read says it helps if the woman orgasms during sex. My thing is I just can not orgasm during sex. I'm embassased by it and I don't know what to do. I get embarrassed every time I think I should look at toys to help but I just don't know what to do any more. He always has to "help" me first before we have sex and I know that doesn't help the sperm get in far enough. so I guess what I'm asking for is advice about not orgasming during penetration sex.
