I have a rule,might be silly ,but my rule: No BF younger than 21. Had a young guy a year ago was hung like the proverbial horse. 10" hard and as big around between a redbull can and the average beer can. Took sometime getting used to his meat,but loved the stretching I would get and the multi orgasm's,and his recovery was amazing,usually he never went down,but I did several times,lol. Alas,he fell in love and moved away
