Love without ,, read this?

i am a 21 years old man, i nEVER had in life, and love some girl very much and we promise each other to get married soon, however, Im planning to never have with her even after marriage, coz platonic love is better than to have where u will disrespect your partner.. is that normal not to have at this age and never plan to have? anyway, i like to talk to her and to act so great, and never bring up subject, is this platonic love going to last forever? i dont masturbate coz i believe in platonic love and believe we shouldnt be doing that. what do u say?
