Sexual frustration

Ladies, need your input here. My husband and I have a great relationship and I wouldn’t change anything ..BUT .. does anyone else have a husband with a very small penis ? How do you deal with it ? My husband is VERY small, smallest one I’ve ever had and He gives me orgasms but not vaginal orgasms from his penis. I can not feel him but have never told him this and he usually keeps falling out constantly. We have sex 4-5 times a week usually. We’ve been married 9 years and I’ve NEVER felt his penis in me and don’t know if I should tell him. I don’t want to hurt him and he’s still be able to ejaculate and he gets me off in other ways 😛. Help ! Anyone in my boat that can relate ?
