Unrealistic beauty standards are absolutely a problem for both men and women, the difference is that in society, men can be valued for other things (occupation, knowledge, athletics) and that is much less true for women.
Though if men can be valued for other ways, that doesn't explain why most men are seen are far below average for the average woman. I think an amendment for your previous statement is that though they can be valued from different areas, the starting value for men is starts way below that of a woman.
For example in Asian cultures there is the idea of 666 standard for males, 6 feet tall, 6 figure salary, 6 pack, which make up less than 0.01% of the eligible population. It may be due to the gender ratio being off, but the standard leaves a lot of women unhappy in their later years
