Hi Lori
No your not being insensitive. It is very similar to having sex. But it just makes sure that the sperm is in the right place without dripping out.
A lot of times this is used when there is a problem such as in our case DH has delayed ejaculation which is the opposite to premature. He just seem to go on for ever and can not ejaculate while having sex (which was great when we weren't trying). Sorry if this is TMI but I wanted to explain that this is the reason we are trying it...
I looked up a few site's and found this info hope it answers some of your questions but please ask me if you want to know more.
In women:
Problems with the cervical mucus - there may not be enough mucus to allow sperm to move easily, or it may be too thick and sticky. Sometimes, the female partner's cervical mucus is not compatible with the male partner's sperm
Women with mild endometriosis (a condition in which the lining of the uterus can become attached to organs such as the fallopian tubes, preventing the passage of eggs)
Anatomical problems with the uterus or cervix, which prevents sperm finding the egg
In men:
Premature ejaculation
Retrograde ejaculation (the entry of semen into the bladder instead of going out through the urethra during ejaculation)
Low sperm count or motility issues
Abnormalities of the penis, such as severe hypospadias. This is when the ejaculate appears at the base of the penis instead of the tip. Occasionally, injury to the penis can also prevent normal penetration and ejaculation
Impotence that makes sexual intercourse impossible
Cancer treatment using chemotherapy or radiotherapy can also make men infertile
Here is the site I found in case you want to read more:~

Of course this is not 100% guarantee that it will work But after a year of trying we will give anything ago. But if it doesn't work I'm hoping we can get IUI done.
