I agree with the advise except bending the call. If you do that it can mess with the stretch the call maker put in the material when they built the call and change its sound and uses. When I first started using mouth calls I used to get the tickle also but as I used them more I got used to it so it doesn't bother me anymore. If you had a gag reflex that would be different and harder to get over. If it keeps bugging you you could try cutting the tape a bit smaller as too much tape can cause this feeling sometimes and it won't mess with the call sounds.
