I understand there is more than one way to pleasure a woman. but theres no way im normal. im to small on soft im about 2-3 inches with no girth and a lil above 5 hard. also it pokes out my pants. im certain my future girl will cheat on me?

A solid erection of 5 inches is very sufficient to satisfy a woman during vaginal intercourse during missionary or female on top positions. Don't obcess about penile size as 5 inch erections are quite average and are capable of pleasuring women whether they have smaller or larger vaginas. Some women can't accommodate a very large erect penis.

I agree with my colleague that your penis size is actually in the normal range. The more important concern you shared was about the potential for an intimate partner to cheat. I would say that does not relate to the size of your penis but more toward the nature of your relationship not just sexual, but also in general. Good communication, showing respect and being honest with each other are key
