Penetration issues?
Answers: not enough lubrication probably.because the vagina will stretch to accommodate size...
you own to do the proper pre play then solely her vegina will be ready to accomdate your penny. it is not a problem. why dont you suck until that time intercourse. that will give the super pre play and some lubrication also. so that you can delight in. Maybe you should try some different positions. Some positions allow for deeper penetration more slickly while at the same time making it more comfortable for her. Also starting stale slow and not penetrating adjectives the way help because it gives her time to adjust to you. After a while of going slow you'll observe you're alot deeper. Sometimes a woman's vagina needs a moment or two time to "accomodate".
Hope this helps!
When a girl is sexually aroused, the vagina lengthen and her cervix rises to accomodate a penis. However, if she's close to ovulation the cervix lowers some to help next to conception. so you could be bumping her cervix at certain times and cause pain.
