Hi

My husband is not able to insert his peins . He complains that its like a wall, to small.
When I tired I can entr only my one finger.

Most women can accommodate a penis, if they're relaxed, ready, and willing.

Some women are tighter than others, but he should be able to enter.

What is he doing to get you ready? Foreplay, are you using lube, are you relaxed?

Yes, how much foreplay is being done? Is there good lube. If you have never had sex, the first time will be harder and have some pain.( sometimes)
