Hi I can understand your concern many times condom does not give sufficient pleasure so many e-mails do not prefer condom but this will be risky if he has some kind of infection as such condom as to purpose to prevent pregnancy as well as to prevent
STD if you are going for sex with a very well known person who is clean without any infection then you can go for sex without condom or else you can just ask for his physical reports that he has no any kind of problem then you can go for that otherwise female condoms are also available which you can use
